+title: Angular & Sanity Integration Rules
+description: Integration guide for Angular, including @sanity/client setup, data fetching with signals and resource API, Portable Text rendering, and image optimization.
+---
+
+# Angular & Sanity Integration Rules
+
+Jump to the section that matches your Angular version or integration task instead of reading this guide straight through.
+
+## Table of Contents
+

+- Client setup (service pattern)
+- Data fetching patterns
+- Routing
+- Portable Text rendering
+- Image optimization
+- Modern Angular features
+- SSR and prerendering
+- Visual Editing
+- Error handling
+
+## 1. Setup & Configuration
+
+Use the official template `sanity-template-angular-clean` as a starting point. It provides a monorepo structure:
+
+```
+project/
+├── angular-app/    # Angular 19+ frontend
+└── studio/         # Sanity Studio
+```
+
+Install dependencies in the Angular app:
+
+```bash
+npm install @sanity/client @sanity/image-url @portabletext/to-html
+```
+
+Configure environment files for Sanity credentials:
+
+```typescript
+// environments/environment.ts
+export const environment = {
+  production: false,
+  sanity: {
+    projectId: 'your-project-id',
+    dataset: 'production',
+    apiVersion: '2025-05-01',
+  },
+}
+```
+
+```typescript
+// environments/environment.production.ts
+export const environment = {
+  production: true,
+  sanity: {
+    projectId: 'your-project-id',
+    dataset: 'production',
+    apiVersion: '2025-05-01',
+  },
+}
+```
+
+> There is no Angular-specific Sanity SDK. Use `@sanity/client` directly, wrapped in an Angular service.
+
+### TypeGen in a Monorepo
+
+Sanity TypeGen generates TypeScript types from your schema and GROQ queries. In the Angular monorepo template, TypeGen runs from the Studio side but scans your Angular app's source files. Ensure `studio/sanity.cli.ts` points at the Angular app:
+
+```typescript
+// studio/sanity.cli.ts
+import { defineCliConfig } from 'sanity/cli'
+
+export default defineCliConfig({
+  typegen: {
+    enabled: true,
+    path: '../angular-app/src/**/*.ts',
+    generates: '../angular-app/sanity.types.ts',
+  },
+})
+```
+
+The remaining defaults (`overloadClientMethods: true`, `schema: "schema.json"`) work as-is. Include the generated types file in `angular-app/tsconfig.json` (usually covered by `"include": ["src/**/*.ts", "sanity.types.ts"]`). See `typegen.md` for the full TypeGen workflow, git strategy, and configuration options.
+
+## 2. Client Setup (Service Pattern)
+
+Create an injectable service wrapping `@sanity/client` and `@sanity/image-url`:
+
+```typescript
+import { Injectable } from '@angular/core'
+import { createClient, type ClientReturn, type QueryParams, type SanityClient } from '@sanity/client'
+import imageUrlBuilder, { type ImageUrlBuilder } from '@sanity/image-url'
+import type { SanityImageSource } from '@sanity/image-url/lib/types/types'
+import { environment } from '../environments/environment'
+
+@Injectable({ providedIn: 'root' })
+export class SanityService {
+  private client: SanityClient
+  private builder: ImageUrlBuilder
+
+  constructor() {
+    this.client = createClient({
+      projectId: environment.sanity.projectId,
+      dataset: environment.sanity.dataset,
+      apiVersion: environment.sanity.apiVersion,
+      useCdn: true,
+    })
+    this.builder = imageUrlBuilder(this.client)
+  }
+
+  // ClientReturn resolves TypeGen's declaration-merged overloads for defineQuery strings
+  fetch<Query extends string>(query: Query, params?: QueryParams): Promise<ClientReturn<Query>> {
+    return this.client.fetch(query, params)
+  }
+
+  getImageUrlBuilder(source: SanityImageSource) {
+    return this.builder.image(source)
+  }
+}
+```
+
+For preview/draft content, create a second client instance with a token and `useCdn: false`. Never expose tokens in client-side bundles — use server-side rendering or a proxy endpoint for authenticated requests.
+
+## 3. Data Fetching Patterns
+
+### A. `resource` API (Angular 19+, Recommended)
+
+The `resource` API works natively with promises and integrates with Angular signals:
+
+```typescript
+import { Component, input, resource, inject } from '@angular/core'
+import { defineQuery } from 'groq'
+import { SanityService } from '../sanity.service'
+
+const POST_QUERY = defineQuery(`*[_type == "post" && slug.current == $slug][0]{
+  title, body, mainImage, publishedAt
+}`)
+
+@Component({
+  selector: 'app-post',
+  standalone: true,
+  template: `
+    @if (post.value(); as p) {
+      <h1>{{ p.title }}</h1>
+      <time>{{ p.publishedAt | date }}</time>
+    } @else if (post.isLoading()) {
+      <p>Loading…</p>
+    } @else if (post.error()) {
+      <p>Error loading post</p>
+    }
+  `,
+})
+export default class PostComponent {
+  slug = input.required<string>()
+  private sanity = inject(SanityService)
+
+  post = resource({
+    params: () => ({ slug: this.slug() }),
+    loader: ({ params }) => this.sanity.fetch(POST_QUERY, params),
+  })
+}
+```
+
+The `resource` automatically re-fetches when `slug` changes and exposes `value()`, `isLoading()`, and `error()` signals.
+
+> **TypeGen:** Wrapping queries in `defineQuery` enables Sanity TypeGen to infer return types automatically — no manual type imports needed. See `typegen.md` for the full workflow.
+
+### B. `rxResource` (Observable-based)
+
+For teams using RxJS patterns or needing operators like `retry` and `debounceTime`:
+
+```typescript
+import { Component, input, inject } from '@angular/core'
+import { rxResource } from '@angular/core/rxjs-interop'
+import { defineQuery } from 'groq'
+import { from } from 'rxjs'
+import { SanityService } from '../sanity.service'
+
+const POST_QUERY = defineQuery(`*[_type == "post" && slug.current == $slug][0]`)
+
+@Component({ /* ... */ })
+export default class PostComponent {
+  slug = input.required<string>()
+  private sanity = inject(SanityService)
+
+  post = rxResource({
+    params: () => ({ slug: this.slug() }),
+    loader: ({ params }) => from(this.sanity.fetch(POST_QUERY, params)),
+  })
+}
+```
+
+### C. `toSignal` (Angular 17–18)
+
+For apps not yet on Angular 19, convert observables to signals:
+
+```typescript
+import { Component, inject } from '@angular/core'
+import { toSignal } from '@angular/core/rxjs-interop'
+import { defineQuery } from 'groq'
+import { from } from 'rxjs'
+import { SanityService } from '../sanity.service'
+
+const POSTS_QUERY = defineQuery(`*[_type == "post"] | order(publishedAt desc)`)
+
+@Component({ /* ... */ })
+export class HomeComponent {
+  private sanity = inject(SanityService)
+  posts = toSignal(from(this.sanity.fetch(POSTS_QUERY)), { initialValue: [] })
+}
+```
+
+> **Note:** `toSignal` does not re-fetch on parameter changes. For dynamic queries, use `resource` or `rxResource`.
+
+### Choosing a pattern
+
+| Pattern | Angular Version | Reactivity | Best For |
+|---|---|---|---|
+| `resource` | 19+ | Signal-based, auto re-fetch | New projects, dynamic queries |
+| `rxResource` | 19+ | RxJS + signals | Teams using RxJS operators |
+| `toSignal` | 17+ | One-shot conversion | Static queries, legacy apps |
+
+## 4. Routing
+
+Use lazy-loaded routes with `withComponentInputBinding()` so route params bind directly to component inputs:
+
+```typescript
+// app.config.ts
+import { provideRouter, withComponentInputBinding } from '@angular/router'
+import { routes } from './app.routes'
+
+export const appConfig = {
+  providers: [
+    provideRouter(routes, withComponentInputBinding()),
+  ],
+}
+```
+
+```typescript
+// app.routes.ts
+import { Routes } from '@angular/router'
+
+export const routes: Routes = [
+  {
+    path: '',
+    loadComponent: () => import('./home/home.component'),
+    pathMatch: 'full',
+  },
+  {
+    path: 'post/:slug',
+    loadComponent: () => import('./post/post.component'),
+  },
+]
+```
+
+With `withComponentInputBinding()`, the `:slug` route param is automatically bound to `slug = input.required<string>()` on the component — no need to inject `ActivatedRoute`.
+
+## 5. Portable Text Rendering
+
+### A. `@portabletext/to-html` with Angular Pipe (Recommended)
+
+```typescript
+import { Pipe, PipeTransform, inject } from '@angular/core'
+import { toHTML, type PortableTextComponents } from '@portabletext/to-html'
+import type { PortableTextBlock } from '@portabletext/types'
+import { SanityService } from '../sanity.service'
+
+@Pipe({ name: 'portableTextToHTML', standalone: true })
+export class PortableTextToHTMLPipe implements PipeTransform {
+  private sanity = inject(SanityService)
+
+  private components: PortableTextComponents = {
+    types: {
+      image: ({ value }) => {
+        const url = this.sanity.getImageUrlBuilder(value).width(800).auto('format').url()
+        return `<img src="${url}" alt="${value.alt || ''}" loading="lazy" />`
+      },
+    },
+    marks: {
+      link: ({ children, value }) =>
+        `<a href="${value.href}" rel="noopener noreferrer">${children}</a>`,
+    },
+  }
+
+  transform(value: PortableTextBlock[] | undefined): string {
+    if (!value) return ''
+    return toHTML(value, { components: this.components })
+  }
+}
+```
+
+Usage in templates:
+
+```html
+<div [innerHTML]="post.body | portableTextToHTML"></div>
+```
+
+### B. `@limitless-angular/sanity` (Community, Component-based)
+
+For full Angular component control over each block type, the community library `@limitless-angular/sanity` provides a component-based Portable Text renderer. This is useful when you need Angular-specific interactivity within rich text blocks.
+
+See `portable-text.md` for Portable Text schema design and serialization rules.
+
+## 6. Image Optimization
+
+Create a pipe wrapping `@sanity/image-url`:
+
+```typescript
+import { Pipe, PipeTransform, inject } from '@angular/core'
+import type { SanityImageSource } from '@sanity/image-url/lib/types/types'
+import { SanityService } from '../sanity.service'
+
+@Pipe({ name: 'sanityImage', standalone: true })
+export class SanityImagePipe implements PipeTransform {
+  private sanity = inject(SanityService)
+
+  transform(value: SanityImageSource | undefined, width?: number): string | null {
+    if (!value) return null
+    const builder = this.sanity.getImageUrlBuilder(value)
+    if (width) return builder.width(width).auto('format').url()
+    return builder.auto('format').url()
+  }
+}
+```
+
+Combine with Angular's `NgOptimizedImage` for LCP images:
+
+```html
+<!-- Priority image with NgOptimizedImage -->
+<img [ngSrc]="post.mainImage | sanityImage: 1200" width="1200" height="630" priority />
+
+<!-- Lazy-loaded image -->
+<img [src]="post.mainImage | sanityImage: 600" [alt]="post.mainImage.alt" loading="lazy" />
+```
+
+❌ **Bad:** Fetching full-size images without width constraints.
+
+```html
+<img [src]="post.mainImage | sanityImage" />
+```
+
+✅ **Good:** Specifying width and using `auto('format')` for WebP/AVIF delivery.
+
+```html
+<img [src]="post.mainImage | sanityImage: 800" loading="lazy" />
+```
+
+### LQIP with `NgOptimizedImage`
+
+Sanity provides a base64 LQIP (Low Quality Image Placeholder) per image asset — but you must query it explicitly:
+
+```groq
+mainImage {
+  // @sanity/image-url needs these to build URLs with hotspot/crop support
+  asset,
+  hotspot,
+  crop,
+  alt,
+  // NgOptimizedImage needs these for placeholder and layout
+  "lqip": asset->metadata.lqip,
+  "width": asset->metadata.dimensions.width,
+  "height": asset->metadata.dimensions.height
+}
+```
+
+Feed the LQIP directly into `NgOptimizedImage`'s `placeholder` attribute:
+
+```html
+<img
+  [ngSrc]="post.mainImage | sanityImage: 1200"
+  [width]="post.mainImage.width"
+  [height]="post.mainImage.height"
+  [placeholder]="post.mainImage.lqip"
+  [alt]="post.mainImage.alt"
+  priority
+/>
+```
+
+Angular applies a CSS blur to the LQIP and crossfades to the full image on load. No extra libraries needed.
+
+> **Note:** LQIP strings are small (~200 bytes) so they're safe to inline in SSR HTML and `TransferState`. See `image.md` for the full image query patterns.
+
+See `image.md` for image field schema patterns and hotspot/crop configuration.
+
+## 7. Modern Angular Features
+
+When building with Sanity, leverage these Angular 19+ features:
+
+- **Standalone components** — Default in Angular 19. No `NgModule` boilerplate needed.
+- **Signals and `resource`** — Preferred over RxJS for data fetching. Simpler, less boilerplate.
+- **New control flow** — Use `@if`, `@for`, `@switch` with `@empty` for cleaner templates:
+
+```html
+@for (post of posts.value(); track post._id) {
+  <app-post-card [post]="post" />
+} @empty {
+  <p>No posts found.</p>
+}
+```
+
+- **`@defer` blocks** — Lazy-load below-fold content:
+
+```html
+@defer (on viewport) {
+  <app-comments [postId]="post._id" />
+} @placeholder {
+  <p>Scroll to see comments…</p>
+}
+```
+
+- **`inject()` function** — Preferred over constructor injection for cleaner code.
+- **Zoneless change detection** — Experimental in Angular 19. Works well with signals-based data fetching since signals automatically notify the framework of changes.
+
+## 8. SSR & Prerendering
+
+Angular 17+ includes built-in SSR support (replacing Angular Universal):
+
+```typescript
+// app.config.server.ts
+import { provideServerRendering } from '@angular/platform-server'
+import { provideClientHydration } from '@angular/platform-browser'
+
+export const serverConfig = {
+  providers: [
+    provideServerRendering(),
+    provideClientHydration(),
+  ],
+}
+```
+
+Key considerations for Sanity + Angular SSR:
+
+| Feature | Details |
+|---|---|
+| **Hydration** | `provideClientHydration()` preserves server-rendered DOM. The client reuses it instead of re-rendering. |
+| **HTTP Transfer Cache** | Only works with Angular's `HttpClient`. Since `@sanity/client` uses its own HTTP transport, use `TransferState` manually (see below). |
+| **Prerendering** | Use `getPrerenderParams` in route config to generate static pages at build time. |
+
+### Transfer State for `@sanity/client`
+
+Angular's built-in HTTP Transfer Cache does not cover `@sanity/client` requests. Without manual transfer, the client re-fetches every query during hydration. Add `TransferState` to the service from Section 2:
+
+```typescript
++ async function hashQuery(query: string, params?: QueryParams): Promise<string> {
++   const input = query + JSON.stringify(params ?? {})
++   const buffer = await crypto.subtle.digest('SHA-256', new TextEncoder().encode(input))
++   return Array.from(new Uint8Array(buffer), b => b.toString(16).padStart(2, '0')).join('')
++ }
+
+import { Injectable, inject } from '@angular/core'
++ import { isPlatformBrowser, isPlatformServer } from '@angular/common'
++ import { PLATFORM_ID, makeStateKey, TransferState } from '@angular/core'
+import { createClient, type ClientReturn, type QueryParams, type SanityClient } from '@sanity/client'
+
+export class SanityService {
+  private client: SanityClient
++  private transferState = inject(TransferState)
++  private platformId = inject(PLATFORM_ID)
+
+  async fetch<Query extends string>(query: Query, params?: QueryParams): Promise<ClientReturn<Query>> {
++    const key = makeStateKey<ClientReturn<Query>>(await hashQuery(query, params))
++
++    if (isPlatformBrowser(this.platformId)) {
++      const cached = this.transferState.get(key, null)
++      if (cached !== null) {
++        this.transferState.remove(key)
++        return cached
++      }
++    }
++
+    const result = await this.client.fetch(query, params)
++
++    if (isPlatformServer(this.platformId)) {
++      this.transferState.set(key, result)
++    }
++
+    return result
+  }
+}
+```
+
+The `hashQuery` helper keeps `TransferState` keys short (SHA-256 hex) instead of embedding raw GROQ strings in the serialized HTML.
+
+Prerendering dynamic routes:
+
+```typescript
+// app.routes.server.ts
+import { RenderMode, ServerRoute } from '@angular/ssr'
+
+export const serverRoutes: ServerRoute[] = [
+  {
+    path: 'post/:slug',
+    renderMode: RenderMode.Prerender,
+    async getPrerenderParams() {
+      // Fetch all slugs from Sanity at build time
+      const client = createClient({ projectId: '...', dataset: '...', apiVersion: '...', useCdn: true })
+      const slugs = await client.fetch<string[]>(`*[_type == "post"].slug.current`)
+      return slugs.map((slug) => ({ slug }))
+    },
+  },
+  { path: '**', renderMode: RenderMode.Server },
+]
+```
+
+❌ **Bad:** Using `isPlatformBrowser()` in templates to conditionally render content — causes hydration mismatch.
+
+✅ **Good:** Using `@defer` or `afterNextRender()` for browser-only code.
+
+## 9. Visual Editing
+
+> **Important:** Angular does not have official Sanity Visual Editing support. There is no `@sanity/visual-editing` integration, no Stega encoding, and no click-to-edit overlay for Angular applications. This is unlike Next.js, Nuxt, and SvelteKit which have first-party support.
+
+### Preview Mode (Basic)
+
+For draft content preview, create a separate preview client with an API token:
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class SanityService {
+  private client: SanityClient
+  private previewClient: SanityClient
+
+  constructor() {
+    this.client = createClient({
+      projectId: environment.sanity.projectId,
+      dataset: environment.sanity.dataset,
+      apiVersion: environment.sanity.apiVersion,
+      useCdn: true,
+    })
+
+    this.previewClient = this.client.withConfig({
+      useCdn: false,
+      token: environment.sanity.previewToken, // Server-side only!
+      perspective: 'drafts',
+    })
+  }
+
+  fetch<Query extends string>(query: Query, params?: QueryParams, preview = false): Promise<ClientReturn<Query>> {
+    const client = preview ? this.previewClient : this.client
+    return client.fetch(query, params)
+  }
+}
+```
+
+> **Security:** Never expose the preview token in client-side bundles. Use this pattern only with SSR where the token stays on the server, or proxy preview requests through a backend API.
+
+### Community Visual Editing
+
+The community library `@limitless-angular/sanity` provides experimental Visual Editing support for Angular, including overlay click-to-edit functionality. Check its documentation for current status and limitations.
+
+## 10. Error Handling
+
+Common errors when integrating Angular with Sanity:
+
+| Error | Cause | Solution |
+|---|---|---|
+| `401 Unauthorized` | Invalid or missing API token | Verify token in [Sanity Manage](https://www.sanity.io/manage). Ensure it has correct permissions. |
+| `403 Forbidden` | CORS origin not allowed | Add your Angular dev/production URL to CORS origins in [Sanity Manage](https://www.sanity.io/manage). |
+| `422 Invalid query` | GROQ syntax error | Test queries in Vision plugin or Sanity's GROQ playground. See `groq.md`. |
+| Hydration mismatch | Conditional rendering based on platform | Use `@defer` or `afterNextRender()` instead of `isPlatformBrowser()` checks. |
+| Empty response | Missing dataset or wrong `apiVersion` | Verify environment config. Use a date-based `apiVersion` (e.g., `'2025-05-01'`). |
+| Images not loading | Missing `@sanity/image-url` setup | Ensure `getImageUrlBuilder` is called with a valid image reference. See `image.md`. |
+
+For GROQ query patterns and best practices, see `groq.md`. For schema design, see `schema.md`.

+- **Always:** Use `useDocuments` for lists, `useDocumentProjection` for display, `useDocument` + `useEditDocument` for editing
+- **Ask first:** Before using `useQuery` with raw GROQ (prefer `useDocuments` + `useDocumentProjection`)
+- **Ask first:** Before adding multiple data-fetching hooks in a single component
+- **Never:** Use `useState` for form values that should sync with Content Lake
+- **Never:** Use array index as React `key` for document lists (breaks real-time updates)
+- **Never:** Forget the `fallback` prop on `<SanityApp>` and `<Suspense>` boundaries
+

+
+## Configuration
+
+### CLI Config (`sanity.cli.ts`)
+
+```typescript
+import { defineCliConfig } from 'sanity/cli'
+
+export default defineCliConfig({
+  app: {
+    organizationId: 'your-org-id',
+    entry: './src/App.tsx',
+  },
+})
+```
+
+### App Root (`src/App.tsx`)
+
+```typescript
+import { SanityApp, type SanityConfig } from '@sanity/sdk-react'
+
+export default function App() {
+  const config: SanityConfig[] = [
+    {
+      projectId: 'your-project-id',
+      dataset: 'production',
+    },
+  ]
+
+  return (
+    <SanityApp config={config} fallback={<div>Loading...</div>}>
+      <YourComponents />
+    </SanityApp>
+  )
+}
+```
+
+### With Sanity UI
+
+```typescript
+import { SanityApp, type SanityConfig } from '@sanity/sdk-react'
+import { ThemeProvider } from '@sanity/ui'
+import { buildTheme } from '@sanity/ui/theme'
+
+const theme = buildTheme()
+
+export default function App() {
+  const config: SanityConfig[] = [
+    { projectId: 'your-project-id', dataset: 'production' },
+  ]
+
+  return (
+    <ThemeProvider theme={theme}>
+      <SanityApp config={config} fallback={<div>Loading...</div>}>
+        <YourComponents />
+      </SanityApp>
+    </ThemeProvider>
+  )
+}
+```
+
+### Environment Variables
+
+Prefix with `SANITY_APP_` for automatic bundling:
+
+```bash
+SANITY_APP_PROJECT_ID=abc123
+SANITY_APP_DATASET=production
+```
+
+Access: `process.env.SANITY_APP_PROJECT_ID`
+
+---
+
+## Document Handles
+
+Lightweight references to documents. Fetch handles first, then load content as needed.
+
+```typescript
+interface DocumentHandle {
+  documentId: string
+  documentType: string
+  projectId?: string
+  dataset?: string
+}
+```
+
+### Creating Handles
+
+```typescript
+// Best: From useDocuments hook
+const { data: handles } = useDocuments({ documentType: 'article' })
+
+// Good: With helper (preserves literal types for TypeGen)
+import { createDocumentHandle } from '@sanity/sdk'
+const handle = createDocumentHandle({
+  documentId: 'my-doc-id',
+  documentType: 'article',
+})
+
+// Good: With as const (preserves literal types)
+const handle = {
+  documentId: 'my-doc-id',
+  documentType: 'article',
+} as const
+```
+
+---
+
+## Hook Selection
+
+| Hook | Use Case | Returns |
+|------|----------|---------|
+| `useDocuments` | List of documents (infinite scroll) | Document handles |
+| `usePaginatedDocuments` | Paginated lists with page controls | Document handles |
+| `useDocument` | Single document, real-time editing | Full document or field |
+| `useDocumentProjection` | Specific fields, display only | Projected data |
+| `useQuery` | Complex GROQ queries (use sparingly) | Raw query results |
+
+---
+
+## Code Patterns
+
+### Fetching a Document List
+
+```typescript
+// Good: Fetch handles, render items with Suspense
+import { Suspense } from 'react'
+import { useDocuments } from '@sanity/sdk-react'
+
+function ArticleList() {
+  const { data, hasMore, loadMore, isPending } = useDocuments({
+    documentType: 'article',
+    batchSize: 10,
+    orderings: [{ field: '_updatedAt', direction: 'desc' }],
+  })
+
+  return (
+    <>
+      <ul>
+        {data.map((handle) => (
+          <Suspense key={handle.documentId} fallback={<li>Loading...</li>}>
+            <ArticleItem {...handle} />
+          </Suspense>
+        ))}
+      </ul>
+      {hasMore && (
+        <button onClick={loadMore} disabled={isPending}>
+          Load More
+        </button>
+      )}
+    </>
+  )
+}
+```
+
+```typescript
+// Bad: Over-fetching with raw GROQ, no pagination
+function BadArticleList() {
+  const { data } = useQuery(`*[_type == "article"]`)
+  return data?.map((doc, i) => <li key={i}>{doc.title}</li>)
+}
+```
+
+### Projecting Content from a Handle
+
+```typescript
+// Good: Project only needed fields
+import { useDocumentProjection, type DocumentHandle } from '@sanity/sdk-react'
+
+function ArticleItem(handle: DocumentHandle) {
+  const { data } = useDocumentProjection({
+    ...handle,
+    projection: `{
+      title,
+      "authorName": author->name,
+      "imageUrl": image.asset->url
+    }`,
+  })
+
+  if (!data) return null
+
+  return (
+    <li>
+      <h2>{data.title}</h2>
+      <p>By {data.authorName}</p>
+    </li>
+  )
+}
+```
+
+### Real-time Editing
+
+```typescript
+// Good: Read and write directly to Content Lake
+import { useDocument, useEditDocument, type DocumentHandle } from '@sanity/sdk-react'
+
+function TitleInput(handle: DocumentHandle) {
+  const { data: title } = useDocument({ ...handle, path: 'title' })
+  const editTitle = useEditDocument({ ...handle, path: 'title' })
+
+  return (
+    <input
+      type="text"
+      value={title ?? ''}
+      onChange={(e) => editTitle(e.currentTarget.value)}
+    />
+  )
+}
+```
+
+```typescript
+// Bad: Local state with submit button - causes stale data
+function BadTitleForm(handle: DocumentHandle) {
+  const [value, setValue] = useState('')
+  const editTitle = useEditDocument({ ...handle, path: 'title' })
+
+  function handleSubmit(e: FormEvent) {
+    e.preventDefault()
+    editTitle(value) // Only writes on submit!
+  }
+
+  return (
+    <form onSubmit={handleSubmit}>
+      <input value={value} onChange={(e) => setValue(e.target.value)} />
+      <button type="submit">Save</button>
+    </form>
+  )
+}
+```
+
+### Document Actions
+
+```typescript
+import {
+  useApplyDocumentActions,
+  publishDocument,
+  unpublishDocument,
+  deleteDocument,
+} from '@sanity/sdk-react'
+
+function DocumentActions({ handle }: { handle: DocumentHandle }) {
+  const apply = useApplyDocumentActions()
+
+  return (
+    <div>
+      <button onClick={() => apply(publishDocument(handle))}>Publish</button>
+      <button onClick={() => apply(unpublishDocument(handle))}>Unpublish</button>
+      <button onClick={() => apply(deleteDocument(handle))}>Delete</button>
+    </div>
+  )
+}
+```
+
+---
+
+## Suspense Patterns
+
+The App SDK uses React Suspense. Every data-fetching component must be wrapped.
+
+### One Hook Per Component
+
+```typescript
+// Good: Separate fetchers into separate components
+function EventsAndVenues() {
+  return (
+    <>
+      <Suspense fallback="Loading events...">
+        <EventsList />
+      </Suspense>
+      <Suspense fallback="Loading venues...">
+        <VenuesList />
+      </Suspense>
+    </>
+  )
+}
+
+function EventsList() {
+  const { data } = useDocuments({ documentType: 'event' })
+  return <List items={data} />
+}
+
+function VenuesList() {
+  const { data } = useDocuments({ documentType: 'venue' })
+  return <List items={data} />
+}
+```
+
+```typescript
+// Bad: Multiple fetchers in one component
+function BadComponent() {
+  const { data: events } = useDocuments({ documentType: 'event' })
+  const { data: venues } = useDocuments({ documentType: 'venue' })
+  // Both trigger Suspense together, causing unnecessary re-renders
+}
+```
+
+### Prevent Layout Shift
+
+```typescript
+// Good: Fallback matches final component dimensions
+const BUTTON_TEXT = 'Open in Studio'
+
+export function OpenInStudio({ handle }: { handle: DocumentHandle }) {
+  return (
+    <Suspense fallback={<Button text={BUTTON_TEXT} disabled />}>
+      <OpenInStudioButton handle={handle} />
+    </Suspense>
+  )
+}
+
+function OpenInStudioButton({ handle }: { handle: DocumentHandle }) {
+  const { navigateToStudioDocument } = useNavigateToStudioDocument(handle)
+  return <Button onClick={navigateToStudioDocument} text={BUTTON_TEXT} />
+}
+```
+
+---
+
+## Event Handling
+
+```typescript
+import { useDocumentEvent, DocumentEvent } from '@sanity/sdk-react'
+
+function DocumentWatcher(handle: DocumentHandle) {
+  useDocumentEvent({
+    ...handle,
+    onEvent: (event) => {
+      switch (event.type) {
+        case 'edited':
+          console.log('Edited:', event.documentId)
+          break
+        case 'published':
+          console.log('Published:', event.documentId)
+          break
+        case 'deleted':
+          console.log('Deleted:', event.documentId)
+          break
+      }
+    },
+  })
+
+  return null
+}
+```
+
+---
+
+## Multi-Project Apps
+
+```typescript
+const config: SanityConfig[] = [
+  { projectId: 'project-1', dataset: 'production' },
+  { projectId: 'project-2', dataset: 'staging' },
+]
+
+// Handles include project/dataset info
+const handle: DocumentHandle = {
+  documentId: 'doc-123',
+  documentType: 'article',
+  projectId: 'project-1',
+  dataset: 'production',
+}
+```
+
+---
+
+## Lazy Loading with Refs
+
+```typescript
+function LazyContent(handle: DocumentHandle) {
+  const ref = useRef(null)
+
+  const { data } = useDocumentProjection({
+    ...handle,
+    ref, // Only loads when element enters viewport
+    projection: '{ title, body }',
+  })
+
+  return <div ref={ref}>{data?.title}</div>
+}
+```
+
+---
+
+## What's NOT Included
+
+The App SDK provides hooks and data stores. You bring:
+
+- UI components (use Sanity UI or your own)
+- Router
+- Form validation
+- Schema validation
+
+---
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Safari dev issues | Use Chrome or Firefox during development |
+| Port 3333 in use | `npm run dev -- --port 3334` |
+| Auth errors | `npx sanity@latest logout && npx sanity@latest login` |

+title: Astro & Sanity Integration Rules
+description: Integration guide for Astro, including @sanity/astro, visual editing, and data fetching.
+---
+
+# Astro & Sanity Integration Rules
+
+## 1. Setup & Configuration
+
+### Configuration (`astro.config.mjs`)
+Use the official `@sanity/astro` integration.
+
+```javascript
+import { defineConfig } from "astro/config";
+import sanity from "@sanity/astro";
+
+export default defineConfig({
+  integrations: [
+    sanity({
+      projectId: "YOUR_PROJECT_ID",
+      dataset: "production",
+      useCdn: false, // False for static builds
+      studioBasePath: "/admin", // If embedding Studio
+    }),
+  ],
+});
+```
+
+### Client Type Safety
+Enable types in `tsconfig.json`.
+
+```json
+{
+  "compilerOptions": {
+    "types": ["@sanity/astro/module"]
+  }
+}
+```
+
+## 2. Data Fetching
+
+### Basic Fetching
+Use `sanityClient` from `sanity:client` in the frontmatter of your `.astro` files.
+
+```astro
+---
+import { sanityClient } from "sanity:client";
+import { defineQuery } from "groq";
+
+const POSTS_QUERY = defineQuery(`*[_type == "post"]{title, slug}`);
+const posts = await sanityClient.fetch(POSTS_QUERY);
+---
+<ul>
+  {posts.map(post => <li>{post.title}</li>)}
+</ul>
+```
+
+### Helper Functions
+It's best practice to abstract queries into a utility file (e.g., `src/utils/sanity.ts`).
+
+```typescript
+import { sanityClient } from "sanity:client";
+import { defineQuery } from "groq";
+
+const POSTS_QUERY = defineQuery(`*[_type == "post" && defined(slug.current)]`);
+
+export async function getPosts() {
+  return await sanityClient.fetch(POSTS_QUERY);
+}
+```
+
+## 3. Portable Text
+Use `astro-portabletext` for rendering rich text.
+
+```astro
+---
+import { PortableText } from "astro-portabletext";
+const { body } = Astro.props;
+---
+<div class="prose">
+  <PortableText value={body} />
+</div>
+```
+
+## 4. Image Handling
+Use `@sanity/image-url` to generate optimized image URLs.
+
+```typescript
+import imageUrlBuilder from "@sanity/image-url";
+import { sanityClient } from "sanity:client";
+
+const builder = imageUrlBuilder(sanityClient);
+
+export function urlFor(source) {
+  return builder.image(source);
+}
+```
+
+## 5. Visual Editing (Live Preview)
+Astro handles visual editing slightly differently depending on if you are using Hybrid or Static mode.
+
+### Setup
+Ensure `stega` is enabled in your client configuration if you want clickable overlays.
+
+For real-time updates in the presentation tool, you typically need a React component wrapper (since Astro components don't re-render on the client) or use the View Transitions API with a loader.
+
+*Note: The `@sanity/astro` integration is evolving. Check the latest docs for "Visual Editing" support.*

+title: Sanity Blueprints
+description: Rules for Sanity Blueprints, the Infrastructure as Code solution for managing Sanity resources declaratively.
+---
+
+# Sanity Blueprints
+
+Sanity's Infrastructure as Code (IaC) solution. Define resources declaratively in `sanity.blueprint.ts`, track in version control, deploy with a single command.
+
+## Mental Model
+
+```
+Blueprint (code) → Stack (deployed state) → Resources (real infrastructure)
+```
+
+| Concept | What it is |
+|---------|------------|
+| **Blueprint** | A declarative configuration file (`sanity.blueprint.ts`) that describes your desired infrastructure |
+| **Stack** | The deployed, real-world collection of resources managed by Blueprints |
+| **Resources** | Individual Sanity components: CORS origins, webhooks, datasets, functions, roles, robots |
+| **Operation** | A deployment execution that applies Blueprint changes to resources in a Stack |
+
+### How it works
+
+1. Initialize and edit a Blueprint file describing desired resources
+2. Run `sanity blueprints deploy` to apply changes to resources in a Stack
+3. Blueprints creates/updates a Stack with your resources
+4. The Stack persists — future deploys update it based on Blueprint changes
+
+**Key insight:** The Blueprint is your *intent*. The Stack is *reality*. Blueprints reconciles the two.
+
+## Available Resources
+
+Blueprints can manage these Sanity components:
+
+- Document Functions
+- Media Library Asset Functions
+
+More resources are coming soon.
+
+## CLI Commands
+
+```bash
+sanity blueprints init <name>    # Initialize a new blueprint project
+sanity blueprints info           # Show current stack status and resources
+sanity blueprints plan           # Preview changes before deploying
+sanity blueprints deploy         # Deploy the blueprint (creates/updates stack)
+sanity blueprints config         # Configure the blueprint (edit project and stack)
+sanity blueprints logs           # View deployment logs
+sanity blueprints doctor         # Check for potential issues
+sanity blueprints stacks         # List all stacks for the project
+sanity blueprints destroy        # Destroy all resources in the stack
+```
+
+## Basic Workflow
+
+### 1. Initialize
+
+```bash
+sanity blueprints init my-infra
+cd my-infra
+sanity blueprints info
+```
+
+This creates a `sanity.blueprint.ts` file and links it to a Sanity project.
+
+### 2. Define resources
+
+Edit `sanity.blueprint.ts` to add resources using typed helper functions from `@sanity/blueprints`.
+
+### 3. Preview and deploy
+
+```bash
+sanity blueprints plan    # See what will change
+sanity blueprints deploy  # Apply changes
+```
+
+### 4. Iterate
+
+Modify your Blueprint and redeploy. Blueprints handles creating, updating, or removing resources to match your definition.
+
+## Key Behaviors
+
+- **Additive by default** — New resources in the Blueprint are created
+- **Updates in place** — Changed resources are updated when possible
+- **Removal = destruction** — Resources removed from the Blueprint are destroyed from the Stack
+- **References** — Resources can reference each other (e.g., a webhook can reference a dataset)
+- **Rollback on failure** — If a deployment fails partway through, Blueprints attempts to rollback

+title: Sanity Functions
+description: Rules for Sanity Functions — serverless event handlers that react to content changes in Sanity's Content Lake. Covers blueprint configuration, handler patterns, testing, deployment, and recursion control.
+---
+
+# Sanity Functions
+
+Serverless event handlers hosted on Sanity's infrastructure, configured via **Blueprints** and triggered by document lifecycle events.
+
+> **Experimental feature**: APIs may change. Always use `npx sanity@latest`.
+
+## When to use
+
+- Set computed/derived fields (timestamps, slugs, summaries)
+- Enrich or validate content on publish
+- Trigger external services (CDN purge, deploy hooks, notifications)
+- Automate workflows (translation, tagging, cross-posting)
+- Sync content to external systems
+- Invoke Agent Actions in response to content events
+
+## When NOT to use
+
+- Logic needs >900s execution or >200MB bundle — use an external worker
+- High-throughput bulk operations that exceed rate limits (200/fn/30s, 4000/project/30s)
+- A simple POST to an external URL on publish with no document data shaping — use a webhook
+- Client-side or UI-driven logic (validation, conditional fields) — belongs in Studio schema config
+
+## Requirements
+
+| Dependency | Version |
+|:---|:---|
+| Node.js | v24.x (matches deployed runtime) |
+| Sanity CLI | v4.12.0+ |
+| `@sanity/blueprints` | Latest |
+| `@sanity/functions` | Latest |
+| `@sanity/client` | v7.12.0+ (includes recursion protection) |
+
+## Project Structure
+
+Organize functions alongside your Sanity project, one level above the Studio directory:
+
+```
+my-project/
+├── studio/
+├── next-app/
+├── functions/
+│   ├── my-function/
+│   │   ├── index.ts          # Handler code (entry point)
+│   │   └── package.json      # (optional) function-level dependencies
+│   └── another-function/
+│       └── index.ts
+├── sanity.blueprint.ts        # Blueprint configuration
+├── package.json               # Project-level dependencies
+└── node_modules/
+```
+
+The function directory name must match the `name` in the blueprint config. Each function exports a `handler` from its `index.ts` (or `index.js`).
+
+---
+
+## Step-by-step: Creating a Function
+
+### 1. Initialize a Blueprint
+
+```bash
+npx sanity@latest blueprints init . \
+  --type ts \
+  --stack-name production \
+  --project-id <your-project-id>
+```
+
+This creates `sanity.blueprint.ts` and `.sanity/blueprint.config.json` (add the latter to `.gitignore`).
+
+### 2. Scaffold a Function
+
+```bash
+npx sanity@latest blueprints add function \
+  --name my-function \
+  --fn-type document-publish \
+  --installer npm
+```
+
+`--fn-type` options: `document-create`, `document-update`, `document-publish` (deprecated), `document-delete`.
+
+### 3. Configure the Blueprint
+
+```typescript
+// sanity.blueprint.ts
+import { defineBlueprint, defineDocumentFunction } from '@sanity/blueprints'
+
+export default defineBlueprint({
+  resources: [
+    defineDocumentFunction({
+      name: 'my-function',
+      event: {
+        on: ['create', 'update'],
+        filter: '_type == "post"',
+      },
+    }),
+  ],
+})
+```
+
+### 4. Write the Handler
+
+```typescript
+// functions/my-function/index.ts
+import { documentEventHandler } from '@sanity/functions'
+import { createClient } from '@sanity/client'
+
+interface PostData {
+  _id: string
+  _type: string
+  title: string
+}
+
+export const handler = documentEventHandler<PostData>(async ({ context, event }) => {
+  const { data } = event
+
+  const client = createClient({
+    ...context.clientOptions,
+    apiVersion: '2025-05-08',
+  })
+
+  try {
+    await client.patch(data._id, {
+      setIfMissing: { firstPublished: new Date().toISOString() },
+    })
+    console.log(`Set firstPublished on ${data._id}`)
+  } catch (error) {
+    console.error('Failed to patch document:', error)
+  }
+})
+```
+
+### 5. Test Locally
+
+```bash
+# Visual dev playground
+npx sanity@latest functions dev
+
+# CLI testing
+npx sanity@latest functions test my-function \
+  --dataset production \
+  --with-user-token
+
+# With a specific document
+npx sanity@latest functions test my-function \
+  --document-id abc123 \
+  --dataset production \
+  --with-user-token
+```
+
+### 6. Deploy
+
+```bash
+npx sanity@latest blueprints deploy
+```
+
+### 7. View Logs
+
+```bash
+npx sanity@latest functions logs my-function
+npx sanity@latest functions logs my-function --watch
+```
+
+---
+
+## Handler Reference
+
+Every handler receives `{ context, event }`:
+
+### `context`
+
+| Property | Type | Description |
+|:---|:---|:---|
+| `clientOptions.apiHost` | `string` | API host URL |
+| `clientOptions.projectId` | `string` | Sanity project ID |
+| `clientOptions.dataset` | `string` | Dataset name |
+| `clientOptions.token` | `string` | Robot token (deployed only) |
+| `local` | `boolean \| undefined` | `true` during local testing |
+| `eventResourceType` | `string` | `'dataset'` or `'media-library'` |
+| `eventResourceId` | `string` | e.g., `'projectId.datasetName'` |
+
+### `event`
+
+```typescript
+{
+  data: {
+    _id: string
+    _type: string
+    // ... rest of document (shaped by projection if set)
+  }
+}
+```
+
+When testing locally, `context.clientOptions` only has `projectId` and `apiHost`. Use `--dataset` and `--with-user-token` flags to supply the rest.
+

+|:---|:---|:---|:---|
+| `on` | `string[]` | required | `'create'`, `'update'`, `'delete'`. Legacy `'publish'` is deprecated. |
+| `filter` | `string` | — | GROQ filter body (no `*[...]` wrapper) |
+| `projection` | `string` | — | GROQ projection to shape `event.data`. Wrap in `{}`. |
+| `includeDrafts` | `boolean` | `false` | Trigger on draft changes |
+| `includeAllVersions` | `boolean` | `false` | Trigger on all document versions |
+| `resource` | `object` | — | Scope to dataset: `{ type: 'dataset', id: 'projectId.datasetName' }` |
+
+### `defineMediaLibraryAssetFunction`
+
+For Media Library asset events. Requires `@sanity/blueprints` v0.4.0+ and `@sanity/functions` v1.1.0+.
+
+```typescript
+import { defineBlueprint, defineMediaLibraryAssetFunction } from '@sanity/blueprints'
+
+export default defineBlueprint({
+  resources: [
+    defineMediaLibraryAssetFunction({
+      name: 'asset-handler',
+      event: {
+        on: ['delete'],
+        filter: 'documents::incomingGlobalDocumentReferenceCount() > 0',
+        projection: '{_id, versions, title}',
+        resource: {
+          type: 'media-library',
+          id: 'mlYourLibraryId',
+        },
+      },
+    }),
+  ],
+})
+```
+
+---
+
+## Event Types
+
+| Event | Description |
+|:---|:---|
+| `create` | New document created |
+| `update` | Existing document modified (for published docs, fires when a draft/version is published) |
+| `delete` | Document deleted |
+| `publish` | **Deprecated.** Equivalent to `['create', 'update']`. Migrate to explicit events. |
+
+Often best to use `['create', 'update']` together for published document triggers.
+
+---
+
+## GROQ Filter Tips
+
+- Only the filter body — `_type == 'post'`, not `*[_type == 'post']`
+- `delta::changedAny(fieldName)` — trigger only when specific fields change
+- `sanity::dataset() == 'production'` — scope to a dataset without `resource` config
+- `_id in path('drafts.**')` with `includeDrafts: true` — draft-only triggers
+- Combine conditions to prevent recursion: `_type == 'post' && !defined(processedAt)`
+
+---
+
+## Projections
+
+- Shape the data passed to `event.data`
+- Limited to the invoking document's scope (plus `→` for references)
+- Nested filters in projections (like `*[references(^._id)]`) will fail silently — query inside the function instead
+- Wrap in `{}`: `projection: '{title, _id, slug}'`
+
+---
+
+## Environment Variables
+
+Three ways to set them:
+
+1. Blueprint config: `env: { MY_VAR: 'value' }`
+2. CLI: `npx sanity functions env add my-function MY_VAR my-value`
+3. Local testing: `MY_VAR=value npx sanity functions test my-function`
+
+Access in handler code via `process.env.MY_VAR`.
+
+---
+
+## Critical Rules
+
+### Preventing Recursion
+
+If your function mutates the same document type it listens to, you **will** create an infinite loop.
+
+**✅ Correct — use GROQ filters to exclude processed documents:**
+```typescript
+defineDocumentFunction({
+  name: 'first-published',
+  event: {
+    on: ['create', 'update'],
+    filter: "_type == 'post' && !defined(firstPublished)",
+  },
+})
+```
+
+**✅ Correct — use `@sanity/client` v7.12.0+ for automatic lineage headers:**
+```typescript
+import { createClient } from '@sanity/client'
+
+// Client automatically sets X-Sanity-Lineage header
+// Recursive chains are limited to 16 invocations
+const client = createClient({
+  ...context.clientOptions,
+  apiVersion: '2025-05-08',
+})
+```
+
+**❌ Incorrect — no recursion guard:**
+```typescript
+defineDocumentFunction({
+  name: 'update-post',
+  event: {
+    on: ['create', 'update'],
+    filter: "_type == 'post'",  // Will re-trigger on its own writes!
+  },
+})
+```
+
+### Local Testing Safety
+
+Use `context.local` to prevent accidental mutations during testing:
+
+```typescript
+// Skip mutations entirely in test
+if (!context.local) {
+  await client.createOrReplace(someDoc)
+}
+
+// Or use dryRun
+await client.patch(event.data._id, {
+  set: { processed: true },
+}).commit({ dryRun: context.local })
+
+// Or use noWrite for Agent Actions
+await client.agent.action.generate({
+  schemaId: 'your-schema-id',
+  documentId: event.data._id,
+  instruction: 'Summarize this document',
+  target: { path: ['summary'] },
+  noWrite: context.local,
+})
+```
+
+### Limits
+
+- Max bundle size: 200MB (including dependencies). Prefer slim, platform-agnostic packages.
+- Rate limits: 200 invocations/fn/30s, 4000/project/30s
+- Max timeout: 900s. Larger functions = slower cold starts.
+
+### Cost
+
+Cost = invocations × (memory GB × duration seconds). Default is 1GB memory. A function averaging 1GB and 40ms duration can run ~500k invocations within 20K GB-seconds. [Monitor usage at the organization level](https://www.sanity.io/manage).
+
+---
+
+## Common Patterns
+
+### Deploy hook / CDN invalidation
+
+**Blueprint:**
+```typescript
+defineDocumentFunction({
+  name: 'deploy-hook',
+  event: {
+    on: ['create', 'update'],
+    filter: '_type == "page"',
+  },
+})
+```
+
+**Handler:**
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const URL = process.env.DEPLOY_HOOK_URL
+  if (!URL) throw new Error('DEPLOY_HOOK_URL is not set')
+
+  await fetch(URL)
+  console.log('Deploy hook triggered')
+})
+```
+
+Set the env var: `npx sanity functions env add deploy-hook DEPLOY_HOOK_URL https://...`
+
+### Set a timestamp on first publish
+
+Uses the same pattern as the step-by-step example above. The key insight: the `!defined(firstPublished)` GROQ filter prevents re-triggering after the field is set. The `setIfMissing` patch is a redundant safety net.
+
+```typescript
+defineDocumentFunction({
+  name: 'first-published',
+  event: {
+    on: ['create', 'update'],
+    filter: '_type == "post" && !defined(firstPublished)',
+  },
+})
+```
+
+### Auto-translate with Agent Actions
+
+**Blueprint:**
+```typescript
+defineDocumentFunction({
+  name: 'translate',
+  event: {
+    on: ['create', 'update'],
+    filter: "_type == 'post' && language == 'en-US'",
+    projection: '{_id}',
+  },
+})
+```
+
+**Handler:**
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const client = createClient({ ...context.clientOptions, apiVersion: 'vX' })
+
+  await client.agent.action.translate({
+    schemaId: 'your-schema-id',
+    async: true,
+    documentId: event.data._id,
+    languageFieldPath: 'language',
+    targetDocument: {
+      operation: 'createOrReplace',
+      _id: `${event.data._id}-el-GR`,
+    },
+    fromLanguage: { id: 'en-US', title: 'English' },
+    toLanguage: { id: 'el-GR', title: 'Greek' },
+  })
+})
+```
+
+The GROQ filter ensures only English documents trigger the function. The translated document gets a different `language` value, preventing recursive triggers.
+
+### Auto-tag with Agent Actions
+
+**Blueprint:**
+```typescript
+defineDocumentFunction({
+  name: 'auto-tag',
+  event: {
+    on: ['create', 'update'],
+    filter: "_type == 'post'",
+    projection: '{_id, title, body}',
+  },
+})
+```
+
+**Handler:**
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const client = createClient({ ...context.clientOptions, apiVersion: 'vX' })
+
+  await client.agent.action.generate({
+    schemaId: 'your-schema-id',
+    documentId: event.data._id,
+    instruction: 'Analyze the content and generate 3 relevant tags. Reuse existing tags when possible.',
+    target: { path: ['tags'] },
+    async: true,
+  })
+})
+```
+
+### Slack notification on publish
+
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const WEBHOOK_URL = process.env.SLACK_WEBHOOK_URL
+  if (!WEBHOOK_URL) throw new Error('SLACK_WEBHOOK_URL not set')
+
+  await fetch(WEBHOOK_URL, {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+      text: `📝 New content published: *${event.data.title || event.data._id}* (${event.data._type})`,
+    }),
+  })
+})
+```
+
+### Scope to a specific dataset
+
+**Option A — `resource` config:**
+```typescript
+defineDocumentFunction({
+  name: 'production-only',
+  event: {
+    on: ['update'],
+    filter: "_type == 'post'",
+    resource: { type: 'dataset', id: 'myProjectId.production' },
+  },
+})
+```
+
+**Option B — GROQ filter:**
+```typescript
+defineDocumentFunction({
+  name: 'production-only',
+  event: {
+    on: ['update'],
+    filter: "_type == 'post' && sanity::dataset() == 'production'",
+  },
+})
+```
+
+### React to Media Library asset changes
+
+Requires `@sanity/blueprints` v0.4.0+ and `@sanity/functions` v1.1.0+.
+
+**Blueprint:**
+```typescript
+import { defineBlueprint, defineMediaLibraryAssetFunction } from '@sanity/blueprints'
+
+export default defineBlueprint({
+  resources: [
+    defineMediaLibraryAssetFunction({
+      name: 'asset-deleted',
+      event: {
+        on: ['delete'],
+        filter: 'documents::incomingGlobalDocumentReferenceCount() > 0',
+        projection: '{_id, versions, title}',
+        resource: { type: 'media-library', id: 'mlYourLibraryId' },
+      },
+    }),
+  ],
+})
+```
+
+**Handler:**
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const { eventResourceId } = context  // Media Library ID
+  const client = createClient({
+    ...context.clientOptions,
+    apiVersion: '2025-05-08',
+  })
+
+  const response = await client.request({
+    uri: `/media-libraries/${eventResourceId}/query`,
+    method: 'POST',
+    body: { query: `*[_type == 'sanity.imageAsset']` },
+  })
+
+  console.log('Assets:', response)
+})
+```
+
+### Recursion control with custom HTTP clients
+
+If not using `@sanity/client`, implement lineage tracking manually:
+
+```typescript
+export const handler = documentEventHandler(async ({ context, event }) => {
+  const lineage = process.env.X_SANITY_LINEAGE
+
+  await fetch(`https://${context.clientOptions.projectId}.api.sanity.io/v2025-05-08/data/mutate/production`, {
+    method: 'POST',
+    headers: {
+      'Content-Type': 'application/json',
+      'Authorization': `Bearer ${context.clientOptions.token}`,
+      ...(lineage ? { 'X-Sanity-Lineage': lineage } : {}),
+    },
+    body: JSON.stringify({
+      mutations: [{ patch: { id: event.data._id, set: { processed: true } } }],
+    }),
+  })
+})
+```
+
+### Multiple functions in one blueprint
+
+```typescript
+export default defineBlueprint({
+  resources: [
+    defineDocumentFunction({
+      name: 'first-published',
+      event: {
+        on: ['create', 'update'],
+        filter: "_type == 'post' && !defined(firstPublished)",
+      },
+    }),
+    defineDocumentFunction({
+      name: 'notify-slack',
+      event: {
+        on: ['create', 'update'],
+        filter: "_type == 'post'",
+        projection: '{title, _id}',
+      },
+    }),
+    defineDocumentFunction({
+      name: 'sync-algolia',
+      timeout: 30,
+      event: {
+        on: ['create', 'update', 'delete'],
+        filter: "_type == 'product'",
+      },
+    }),
+  ],
+})
+```
+
+---
+
+## CI/CD Deployment
+
+Use the [Blueprints GitHub Action](https://github.com/sanity-io/blueprints-actions)
+
+```yaml
+- uses: sanity-io/blueprints-actions/deploy@deploy-v3
+  with:
+    sanity-token: ${{ secrets.SANITY_DEPLOY_TOKEN }}
+```
+
+Only personal auth tokens are supported for deployment (not robot tokens).

+title: Sanity Getting Started Guide
+description: Use these rules when users ask to 'Get started with Sanity' or need help setting up a new Sanity project.
+---
+
+# Sanity Getting Started Guide
+
+## Overview
+
+Getting started with Sanity follows three phases:
+1. **Studio & Schema** — Set up Sanity Studio and define your content model
+2. **Content** — Import existing content or generate placeholder content via MCP
+3. **Frontend** — Integrate with your application (framework-specific)
+
+## Communication Style
+
+**Keep responses succinct:**
+
+- Tell the user what you did: "Created post schema with title, body, and slug"
+- Ask direct questions: "What kind of content are you building?"
+- Avoid verbose explanations of what you're about to do
+- Don't explain every step unless the user asks
+
+**Examples:**
+
+- **Good**: "Schema deployed. Ready to add some content?"
+- **Bad**: "I'm going to deploy your schema to the Content Lake so that the MCP server can recognize your new document types. This will allow..."
+
+---
+
+## Get Started with Sanity (Interactive Guide)
+
+**TRIGGER PHRASE:** When the user says "Get started with Sanity" or similar, follow these steps.
+
+**Before starting:** Let the user know they can pause and resume anytime by saying "Continue Sanity setup".
+
+**RESUME TRIGGER:** If the user says "Continue Sanity setup", check what's already configured:
+- Does `sanity.config.ts` exist? → Studio is set up
+- Are there files in `schemaTypes/`? → Schema exists
+- Is there a frontend framework in `package.json`? → May need integration
+
+Resume from where they left off.
+
+---
+
+## Phase 1: Studio & Schema
+
+### Step 1: Check for Existing Studio
+
+**Look for `sanity.config.ts` or `sanity.cli.ts`:**
+
+**If NO Studio found:**
+- Ask: "Want to create a new Sanity Studio?"
+- If yes, run:
+  ```bash
+  npm create sanity@latest -- --template clean --typescript
+  ```
+
+**If Studio exists:**
+- Read the config to get `projectId` and `dataset`
+- Proceed to Step 2
+
+### Step 2: Check for Existing Schema
+
+**Look in `schemaTypes/`, `schemas/`, or `src/sanity/schemaTypes/`:**
+
+**If NO schema found:**
+- Ask: "What kind of content are you building? (e.g., Blog, E-commerce, Portfolio)"
+- Create appropriate schema types based on their answer
+- See `schema.md` for patterns
+
+**If schema exists:**
+- Show them what you found
+- Ask: "Want to add more content types or modify existing ones?"
+
+**If they want a quick example:**
+Create a basic blog schema:
+```typescript
+// schemaTypes/post.ts
+import { defineType, defineField } from 'sanity'
+
+export const post = defineType({
+  name: 'post',
+  title: 'Post',
+  type: 'document',
+  fields: [
+    defineField({ name: 'title', type: 'string' }),
+    defineField({ name: 'slug', type: 'slug', options: { source: 'title' } }),
+    defineField({ name: 'body', type: 'array', of: [{ type: 'block' }] }),
+  ],
+})
+```
+
+### Step 3: Deploy Schema
+
+**Required before Phase 2:**
+
+```bash
+npx sanity schema deploy
+```
+
+This uploads your schema to the Content Lake so MCP tools can work with it.
+
+---
+
+## Phase 2: Content
+
+### Step 1: Check for Existing Content
+
+**Use MCP `query_documents` to check:**
+```
+*[_type == "post"][0...5]
+```
+
+**If content exists:**
+- Show them a summary
+- Ask: "Want to add more content or move to frontend integration?"
+
+**If NO content:**
+- Ask: "Do you want to:
+  1. Import existing content (from another CMS, markdown, etc.)
+  2. Generate sample content with AI
+  3. Skip this and add content manually in the Studio"
+
+### Step 2a: Import Existing Content
+
+If migrating from another CMS or files:
+- See `migration.md`
+- Use MCP `migrate_content` tool for guidance
+
+### Step 2b: Generate Sample Content (MCP)
+
+Use the Sanity MCP Server:
+```
+Tool: create_document
+Type: post
+Content: Create a sample blog post about getting started with Sanity
+```
+
+**If MCP fails:** Remind them to run `npx sanity schema deploy` first.
+
+### MCP Setup (If Not Configured)
+
+**Quick start via Sanity CLI:**
+```bash
+npx sanity@latest mcp configure
+```
+
+**Cursor:** [One-click install →](cursor://anysphere.cursor-deeplink/mcp/install?name=Sanity&config=eyJ1cmwiOiJodHRwczovL21jcC5zYW5pdHkuaW8iLCJ0eXBlIjoiaHR0cCJ9Cg==)
+
+Or add to `.cursor/mcp.json`:
+```json
+{
+  "mcpServers": {
+    "Sanity": {
+      "type": "http",
+      "url": "https://mcp.sanity.io"
+    }
+  }
+}
+```
+
+**Claude Code:**
+```bash
+claude mcp add Sanity -t http https://mcp.sanity.io --scope user
+```
+
+**VS Code:** Command Palette → `MCP: Open User Configuration` → add:
+```json
+{
+  "servers": {
+    "Sanity": {
+      "type": "http",
+      "url": "https://mcp.sanity.io"
+    }
+  }
+}
+```
+
+---
+
+## Phase 3: Frontend Integration
+
+### Step 1: Detect Framework
+
+**Check `package.json` dependencies:**
+
+| Dependency | Framework | Rule File |
+|------------|-----------|-----------|
+| `next` | Next.js | `nextjs.md` |
+| `@remix-run/react` or `react-router` | React Router / Remix | `remix.md` |
+| `svelte` or `@sveltejs/kit` | SvelteKit | `svelte.md` |
+| `nuxt` | Nuxt | `nuxt.md` |
+| `astro` | Astro | `astro.md` |
+
+**If NO framework found:**
+- Ask: "Which framework are you using, or would you like to create a new app?"
+- Guide them to create one or specify their choice
+
+### Step 2: Next.js Integration (Inline)
+
+If Next.js is detected, follow these essential steps:
+
+**Install dependencies:**
+```bash
+npm install @sanity/client @sanity/image-url @portabletext/react
+```
+
+**Create the client (`src/sanity/client.ts`):**
+```typescript
+import { createClient } from "@sanity/client";
+
+export const client = createClient({
+  projectId: process.env.NEXT_PUBLIC_SANITY_PROJECT_ID!,
+  dataset: process.env.NEXT_PUBLIC_SANITY_DATASET!,
+  apiVersion: "2026-02-01", // Use current date for new projects
+  useCdn: false, // Use API directly for server-side rendering; set true for client-side reads
+});
+```
+
+**Fetch content in a Server Component:**
+```typescript
+// app/posts/page.tsx
+import { client } from "@/sanity/client";
+
+import { defineQuery } from "groq";
+
+const POSTS_QUERY = defineQuery(`*[_type == "post"]{ _id, title, slug }`);
+
+export default async function PostsPage() {
+  const posts = await client.fetch(POSTS_QUERY);
+
+  return (
+    <ul>
+      {posts.map((post) => (
+        <li key={post._id}>
+          <a href={`/posts/${post.slug.current}`}>{post.title}</a>
+        </li>
+      ))}
+    </ul>
+  );
+}
+```
+
+**Add environment variables (`.env.local`):**
+```
+NEXT_PUBLIC_SANITY_PROJECT_ID=your-project-id
+NEXT_PUBLIC_SANITY_DATASET=production
+```
+
+For advanced patterns (TypeGen, Visual Editing, `defineLive`), see `nextjs.md`.
+
+### Step 3: Other Frameworks
+
+For non-Next.js frameworks, read the corresponding rule file and follow its integration guide:
+
+- **React Router / Remix:** `remix.md`
+- **SvelteKit:** `svelte.md`
+- **Nuxt:** `nuxt.md`
+- **Astro:** `astro.md`
+
+Each rule file contains framework-specific patterns for data fetching, Portable Text rendering, and Visual Editing.
+
+---
+
+## What's Next
+
+Once setup is complete, let the user know:
+
+"You're all set! Here are some things I can help with:
+
+- **Visual Editing** — Click-to-edit in the Presentation tool (`visual-editing.md`)
+- **TypeGen** — Type-safe queries with generated types (`typegen.md`)
+- **Studio Structure** — Customize the Studio sidebar (`studio-structure.md`)
+- **SEO** — Metadata, sitemaps, and Open Graph (`seo.md`)
+- **i18n** — Multi-language content (`localization.md`)
+
+Just ask about any of these!"
+
+---
+
+## Environment Variables
+
+### Framework-Specific Prefixes
+
+| Framework | Client-Side Prefix | Example |
+|-----------|-------------------|---------|
+| Next.js | `NEXT_PUBLIC_` | `NEXT_PUBLIC_SANITY_PROJECT_ID` |
+| React Router / Remix | None (use loader) | `SANITY_PROJECT_ID` |
+| SvelteKit | `PUBLIC_` | `PUBLIC_SANITY_PROJECT_ID` |
+| Nuxt | `NUXT_PUBLIC_` | `NUXT_PUBLIC_SANITY_PROJECT_ID` |
+| Astro | `PUBLIC_` | `PUBLIC_SANITY_PROJECT_ID` |
+
+---
+
+## Common Commands
+
+```bash
+npx sanity@latest mcp configure  # Configure MCP for your editor
+npx sanity dev                   # Start Studio locally
+npx sanity schema deploy         # Deploy schema (required for MCP!)
+npx sanity deploy                # Deploy Studio to Sanity hosting
+npx sanity manage                # Open project settings
+npm run typegen                  # Generate TypeScript types
+```
+
+---
+
+## Important Notes
+
+- **Be succinct** — Guide step-by-step without over-explaining
+- **Check context first** — Read existing files before suggesting changes
+- **Don't give up** — If something fails, give the user a way to complete manually
+- **Deploy schema early** — MCP tools won't work without it
+- **One phase at a time** — Complete each phase before moving to the next

+- API version best practices
+
+## 1. Query Definition & Imports
+
+### The `defineQuery` Function
+**ALWAYS** wrap GROQ queries in `defineQuery` for TypeGen support. The import location depends on your framework:
+
+```typescript
+// Framework-agnostic (Angular, Remix, SvelteKit, Astro, vanilla)
+import { defineQuery } from "groq";
+
+// Next.js (re-exported for convenience)
+import { defineQuery } from "next-sanity";
+```
+
+### Syntax Highlighting
+For VS Code syntax highlighting, either:
+1. Use the `groq` tagged template (recommended): `groq\`...\``
+2. Or prefix with `/* groq */` comment when using `defineQuery`
+
+```typescript
+import { defineQuery } from "groq";
+
+// ✅ Option A: groq tag (provides highlighting automatically)
+import groq from "groq";
+const QUERY = defineQuery(groq`*[_type == "post"]`);
+
+// ✅ Option B: Comment prefix (for plain template literals)
+const QUERY = defineQuery(/* groq */ `*[_type == "post"]`);
+
+// ✅ Also valid: Just defineQuery (TypeGen works, but no editor highlighting)
+const QUERY = defineQuery(`*[_type == "post"]`);
+```
+
+## 2. Query Fragments
+Use string interpolation to reuse query logic and keep queries maintainable.
+
+```typescript
+// src/sanity/fragments/image.ts
+export const imageFragment = /* groq */ `
+  asset->{
+    _id,
+    url,
+    metadata { lqip, dimensions }
+  },
+  alt
+`;
+
+// src/sanity/queries/post.ts
+import { defineQuery } from "groq";
+import { imageFragment } from "../fragments/image";
+
+export const POST_QUERY = defineQuery(/* groq */ `
+  *[_type == "post"][0] {
+    title,
+    mainImage {
+      ${imageFragment}
+    }
+  }
+`);
+```
+
+## 3. Expansion Patterns (Page Builder)
+When building a Page Builder query, expand all potential component types.
+
+**Best Practice:** Use a `pageFields` fragment or similar strategy to keep the main query clean.
+
+```typescript
+const pageBuilderExpansion = /* groq */ `
+  pageBuilder[] {
+    ...,
+    _type == "hero" => {
+      ...,
+      cta[] { link, label }
+    },
+    _type == "gallery" => {
+      images[] { ${imageFragment} }
+    }
+  }
+`;
+```
+
+## 4. Maintenance Workflow
+When you add a new field or component to the Schema:
+1.  **Update the Query:** Add the new field/expansion to the relevant GROQ query immediately.
+2.  **Run TypeGen:** If you have `typegen.enabled: true` in `sanity.cli.ts`, types regenerate automatically during `sanity dev`/`sanity build`. Otherwise, run `npm run typegen` manually.
+3.  **Verify:** Ensure the new field is available in the generated types.
+
+## 5. Common Patterns
+
+### Ordering
+```groq
+// Single field
+*[_type == "post"] | order(publishedAt desc)
+
+// Multiple fields (tiebreaker)
+*[_type == "post"] | order(featured desc, publishedAt desc)
+
+// ⚠️ Order BEFORE slice, not after!
+*[_type == "post"] | order(publishedAt desc)[0...10]  // ✅ Correct
+*[_type == "post"][0...10] | order(publishedAt desc)  // ❌ Wrong order
+```
+
+### Slice Notation
+```groq
+*[_type == "post"][0]       // Single document (object, not array)
+*[_type == "post"][0...5]   // First 5 (exclusive) ← Most common
+*[_type == "post"][$start...$end]  // Pagination with params
+```
+
+### Default Values with `coalesce()`
+```groq
+*[_type == "page"]{
+  "title": coalesce(seoTitle, title, "Untitled"),
+  "image": coalesce(ogImage, mainImage, defaultImage)
+}
+```
+
+### Conditionals with `select()`
+```groq
+*[_type == "product"]{
+  title,
+  "badge": select(
+    stock == 0 => "Out of Stock",
+    stock < 5 => "Low Stock",
+    "In Stock"
+  )
+}
+```
+
+### Aggregation with `count()`
+```groq
+// Total count
+count(*[_type == "post" && defined(slug.current)])
+
+// Count per document
+*[_type == "category"]{
+  title,
+  "postCount": count(*[_type == "post" && references(^._id)])
+}
+```
+
+### Reverse References
+```groq
+*[_type == "author"]{
+  name,
+  "posts": *[_type == "post" && references(^._id)]{ title, slug }
+}
+```
+
+### Array Filtering
+```groq
+*[_type == "movie"]{
+  title,
+  "mainCast": castMembers[role == "lead"]->{name}
+}
+
+// Check if value exists in array
+*[_type == "post" && "tech" in categories[]->slug.current]
+```
+
+### Special Variables
+```groq
+// ^ = parent document (in nested queries)
+*[_type == "author"]{
+  name,
+  "posts": *[_type == "post" && author._ref == ^._id]
+}
+
+// @ = current item (in array operations)
+*[_type == "post"]{
+  "tagCount": count(tags[@ != null])
+}
+```
+
+## 6. Performance Rules
+
+### Optimizable vs Non-Optimizable Filters
+GROQ uses indexes for **optimizable** filters. Non-optimizable filters scan ALL documents.
+
+| Pattern | Optimizable | Example |
+|---------|-------------|---------|
+| `_type == "x"` | ✅ Yes | `*[_type == "post"]` |
+| `_id == "x"` | ✅ Yes | `*[_id == "abc123"]` |
+| `slug.current == $slug` | ✅ Yes | `*[slug.current == "hello"]` |
+| `defined(field)` | ✅ Yes | `*[defined(publishedAt)]` |
+| `references($id)` | ✅ Yes | `*[references("author-123")]` |
+| `field->attr == x` | ❌ No | Resolves reference for every doc |
+| `fieldA < fieldB` | ❌ No | Compares two attributes |
+
+**Fix non-optimizable filters by stacking:**
+```groq
+// Stack optimizable filters FIRST to reduce search space
+*[_type == "product" && defined(salePrice) && salePrice < displayPrice]
+```
+
+### Avoid Joins in Filters
+Reference resolution (`->`) in filters is expensive. Use `_ref` instead:
+
+```groq
+// ❌ Slow: Resolves reference for every document
+*[_type == "post" && author->name == "Bob Woodward"]
+
+// ✅ Fast: Direct _ref comparison
+*[_type == "post" && author._ref == "author-bob-woodward-id"]
+```
+
+**When you need dynamic lookups** (don't know the ID upfront):
+
+```groq
+// Two-step approach:
+// 1. Get the reference ID first
+*[_type == "author" && name == "Bob Woodward"][0]._id
+
+// 2. Use that ID in your main query
+*[_type == "post" && author._ref == $authorId]
+
+// Or use a subquery (still better than -> in filter):
+*[_type == "post" && author._ref in *[_type == "author" && name == "Bob Woodward"]._id]
+```
+
+### Merge Repeated Reference Resolutions
+Each `->` is a subquery. Don't repeat it:
+
+```groq
+// ❌ Slow: Two separate subqueries
+*[_type == "category"]{
+  "parentTitle": parent->title,
+  "parentSlug": parent->slug.current
+}
+
+// ✅ Fast: Single subquery, merged
+*[_type == "category"]{
+  ...(parent->{ "parentTitle": title, "parentSlug": slug.current })
+}
+```
+
+### Cursor-Based Pagination (Not Deep Slicing)
+Deep slices are slow because all skipped docs must be sorted first.
+
+```groq
+// ❌ Slow: Must sort and skip 10,000 docs
+*[_type == "article"] | order(_id)[10000...10020]
+
+// ✅ Fast: Cursor-based, only fetches 20
+*[_type == "article" && _id > $lastId] | order(_id)[0...20]
+```
+
+**For custom sort orders**, include the sort field in the cursor:
+
+```groq
+// Compound cursor: publishedAt + _id for deterministic pagination
+*[_type == "article" && (
+  publishedAt < $lastDate || 
+  (publishedAt == $lastDate && _id > $lastId)
+)] | order(publishedAt desc, _id)[0...20]
+```
+
+### Always Project Fields
+Always use projections to return only the fields your application needs. Fetching entire documents wastes bandwidth and processing time.
+
+```groq
+// ❌ Returns ALL fields including unused ones, metadata, revisions
+*[_type == "post"]
+
+// ✅ Only fetch what the component needs
+*[_type == "post"]{
+  _id,
+  title,
+  "slug": slug.current,
+  publishedAt,
+  excerpt
+}
+```
+
+Apply projections at every level, including nested references:
+
+```groq
+*[_type == "post"]{
+  title,
+  author->{ name, "avatar": image.asset->url },
+  categories[]->{ title, "slug": slug.current }
+}
+```
+
+Use conditional projections for different contexts:
+
+```groq
+*[_type == "post"]{
+  title,
+  slug,
+  // Only include body for single post view
+  $includeBody == true => { body }
+}
+```
+
+### Don't Filter/Sort on Projected Values
+Computed attributes can't use indexes:
+
+```groq
+// ❌ Not optimizable (computed attribute)
+*[_type == "person"]{
+  "fullName": firstName + " " + lastName
+} | order(fullName)
+
+// ✅ Optimizable (original attribute)
+*[_type == "person"] | order(firstName, lastName)
+```
+
+### Quick Checklist
+| Rule | Why |
+|------|-----|
+| Always project `{ fields }` | Reduces data returned |
+| Use `defined()` checks | Filters use indexes |
+| Use `$params` not interpolation | Prevents query manipulation + enables caching |
+| Order BEFORE slice | `order()[0...N]` not `[0...N] order()` |
+| Use `_ref` not `->field` in filters | Avoids expensive joins |
+| Merge repeated `->` calls | Single subquery vs many |
+| Cursor pagination for deep pages | Avoids sorting entire dataset |
+
+## 7. API Version Best Practices
+
+Always use dated versions (`YYYY-MM-DD`) for consistent behavior:
+
+```typescript
+const client = createClient({
+  apiVersion: '2026-02-01', // Use current date for new projects
+})
+```
+
+- **New projects:** Use current date (e.g., `2026-02-01`)
+- **Existing projects:** Keep current version unless you need new features
+- Dated versions lock behavior; `v1` or `vX` may change unexpectedly

+
+# Sanity + Shopify + Hydrogen Rules
+
+**Package:** [`hydrogen-sanity`](https://github.com/sanity-io/hydrogen-sanity) — requires `@shopify/hydrogen >= 2025.5.0`
+
+## 1. Architecture Overview
+
+| Component | Purpose |
+|-----------|---------|
+| **Shopify** | Product catalog, inventory, checkout (source of truth for commerce) |
+| **Sanity Connect** | Syncs Shopify data to Sanity in real-time |
+| **Sanity Studio** | Editorial content, rich descriptions, media (enhances Shopify data) |
+| **Hydrogen** | React Router 7 front-end optimized for Shopify |
+
+**Project Structure:**
+```
+./
+├── /studio    # Sanity Studio
+└── /web       # Hydrogen front-end
+```
+
+## 2. Environment Variables
+
+```bash
+# web/.env
+PUBLIC_STOREFRONT_API_TOKEN="your-public-storefront-token"
+PRIVATE_STOREFRONT_API_TOKEN="your-private-storefront-token"
+PUBLIC_STORE_DOMAIN="your-store.myshopify.com"
+SESSION_SECRET="your-random-session-secret"
+
+# Sanity
+SANITY_PROJECT_ID="your-project-id"
+SANITY_DATASET="production"
+SANITY_API_VERSION="2026-02-01"
+SANITY_PREVIEW_TOKEN="your-sanity-viewer-token"  # Viewer token for previews
+```
+
+## 3. Sanity Client Setup
+
+### Vite Config
+```typescript
+// web/vite.config.ts
+import {hydrogen} from '@shopify/hydrogen/vite'
+import {sanity} from 'hydrogen-sanity/vite'
+
+export default defineConfig({
+  plugins: [hydrogen(), sanity()],
+})
+```
+
+### Context Setup
+```typescript
+// web/app/lib/context.ts
+import {createSanityContext, type SanityContext} from 'hydrogen-sanity'
+import {PreviewSession} from 'hydrogen-sanity/preview/session'
+import {isPreviewEnabled} from 'hydrogen-sanity/preview'
+
+const sanity = await createSanityContext({
+  request,
+  cache,
+  waitUntil,
+  client: {
+    projectId: env.SANITY_PROJECT_ID,
+    dataset: env.SANITY_DATASET,
+    apiVersion: env.SANITY_API_VERSION || '2026-02-01',
+    useCdn: true,
+    stega: {
+      enabled: isPreviewEnabled(env.SANITY_PROJECT_ID, previewSession),
+      studioUrl: 'http://localhost:3333',
+    }
+  },
+  preview: {
+    token: env.SANITY_PREVIEW_TOKEN,
+    session: previewSession,
+  }
+})
+```
+
+### Provider Setup (entry.server.tsx)
+```typescript
+const {SanityProvider} = context.sanity
+
+const body = await renderToReadableStream(
+  <NonceProvider>
+    <SanityProvider>
+      <ServerRouter context={reactRouterContext} url={request.url} nonce={nonce} />
+    </SanityProvider>
+  </NonceProvider>,
+)
+```
+
+### Root Layout (root.tsx)
+```typescript
+import {Sanity} from 'hydrogen-sanity'
+
+export function Layout({children}) {
+  const nonce = useNonce()
+  return (
+    <html>
+      <body>
+        {children}
+        <Sanity nonce={nonce} />  {/* Required for client-side */}
+        <Scripts nonce={nonce} />
+      </body>
+    </html>
+  )
+}
+```
+
+## 4. Data Fetching
+
+Fetch from **both** Shopify (GraphQL) and Sanity (GROQ). Use `defineQuery` for TypeGen support.
+
+### Recommended: `query` + `Query` component
+```typescript
+import {defineQuery} from 'groq'
+import {Query} from 'hydrogen-sanity'
+
+const PRODUCT_QUERY = defineQuery(`*[_type == "product" && store.slug.current == $handle][0]{ body }`)
+
+// Loader
+export async function loader({params, context: {sanity}}: LoaderFunctionArgs) {
+  const initial = await context.sanity.query(PRODUCT_QUERY, params)
+  return {initial}
+}
+
+// Component - auto-enables live preview when active
+export default function ProductPage({loaderData}) {
+  return (
+    <Query query={PRODUCT_QUERY} options={{initial: loaderData.initial}}>
+      {(data) => <div>{data?.body}</div>}
+    </Query>
+  )
+}
+```
+
+### Alternative methods
+| Method | Use Case |
+|--------|----------|
+| `sanity.query()` + `Query` | Recommended - auto preview mode |
+| `sanity.loadQuery()` | Manual loader integration |
+| `sanity.fetch()` | No preview needed, lightweight |
+| `sanity.client` | Mutations in actions |
+
+### Images
+```typescript
+import {useImageUrl} from 'hydrogen-sanity'
+
+function Hero({image}) {
+  const imageUrl = useImageUrl(image)
+  return <img src={imageUrl.width(1200).height(600).url()} />
+}
+```
+
+**Key Insight:** Shopify fields synced via Sanity Connect are `readOnly`. Use Sanity for editorial enhancements only.
+
+## 5. Visual Editing Setup
+
+### Root Layout
+```typescript
+// web/app/root.tsx
+import {usePreviewMode} from 'hydrogen-sanity/preview'
+import {VisualEditing} from 'hydrogen-sanity/visual-editing'
+
+export function Layout({children}: {children?: React.ReactNode}) {
+  const previewMode = usePreviewMode()
+
+  return (
+    <html>
+      <body>
+        {children}
+        {previewMode ? <VisualEditing action="/api/preview" /> : null}
+      </body>
+    </html>
+  )
+}
+```
+
+### Preview Route
+```typescript
+// web/app/routes/api.preview.ts
+export {action, loader} from 'hydrogen-sanity/preview/route'
+```
+
+### Content Security Policy
+```typescript
+// web/entry.server.tsx
+const {nonce, header, NonceProvider} = createContentSecurityPolicy({
+  frameAncestors: isPreviewEnabled ? [studioHostname] : [],
+  connectSrc: [
+    `https://${projectId}.api.sanity.io`,
+    `wss://${projectId}.api.sanity.io`,
+  ],
+})
+```
+
+## 6. Studio: Presentation Tool
+
+```typescript
+// studio/sanity.config.ts
+import {presentationTool} from 'sanity/presentation'
+
+export default defineConfig({
+  plugins: [
+    presentationTool({
+      resolve: {
+        locations: {
+          product: defineLocations({
+            select: { title: 'store.title', slug: 'store.slug.current' },
+            resolve: (doc) => ({
+              locations: [
+                { title: doc?.title || 'Untitled', href: `/products/${doc?.slug}` },
+                { title: 'Products', href: `/collections/all` },
+              ],
+            }),
+          }),
+        },
+      },
+      previewUrl: {
+        origin: 'http://localhost:3000',
+        previewMode: { enable: '/api/preview' },
+      },
+    }),
+  ],
+})
+```
+
+## 7. Commands
+
+```bash
+# Install dependencies
+pnpm add hydrogen-sanity @sanity/client @portabletext/react
+
+# Development (run in separate terminals)
+cd studio && pnpm dev    # Studio at localhost:3333
+cd web && pnpm dev       # Hydrogen at localhost:3000
+
+# Sanity Manage (CORS, tokens): https://www.sanity.io/manage
+pnpm dlx sanity manage
+```
+
+## 8. Boundaries
+
+- Always:
+  - Query Shopify for commerce data (price, inventory, variants)
+  - Query Sanity for editorial content (rich text, custom fields)
+  - Use `hydrogen-sanity` package for Visual Editing
+  - Add Hydrogen URL to CORS origins in [Sanity Manage](https://www.sanity.io/manage)
+
+- Ask First:
+  - Before modifying Sanity Connect sync settings
+  - Before changing CSP configuration
+
+- Never:
+  - Edit Shopify-synced fields in Sanity (they're `readOnly`)
+  - Expose `SANITY_API_TOKEN` to client-side code
+  - Query Sanity for commerce data that should come from Shopify

+title: "Sanity Image Rules"
+description: "Best practices for handling images in Sanity: Schema, URL generation, and Next.js Image integration."
+---
+
+# Sanity Image Rules
+
+## 1. Schema Definition
+**Always** enable `hotspot: true`. This allows editors to control cropping and the focal point.
+
+```typescript
+defineField({
+  name: 'mainImage',
+  title: 'Main Image',
+  type: 'image',
+  options: {
+    hotspot: true // CRITICAL
+  },
+  fields: [
+    defineField({
+      name: 'alt',
+      type: 'string',
+      title: 'Alternative Text',
+      validation: rule => rule.required().warning('Alt text is important for SEO')
+    })
+  ]
+})
+```
+
+## 2. URL Builder (`urlFor`)
+Use the Sanity Image URL Builder to generate optimized URLs (resize, crop, format).
+
+**Setup (`sanity/lib/image.ts`):**
+```typescript
+import createImageUrlBuilder from '@sanity/image-url'
+import { dataset, projectId } from '../env'
+
+const builder = createImageUrlBuilder({ projectId, dataset })
+
+export const urlFor = (source: any) => {
+  return builder.image(source)
+}
+```
+
+**Usage:** The URL builder automatically uses hotspot/crop data when available:
+```typescript
+const imageUrl = urlFor(mainImage)
+  .width(800)
+  .height(600)
+  .fit('crop')  // Respects hotspot when cropping
+  .url()
+```
+
+## 3. Next.js Image Component Pattern
+Create a reusable `SanityImage` component that handles the `urlFor` logic and `next/image` props.
+
+```typescript
+import Image from 'next/image'
+import { urlFor } from '@/sanity/lib/image'
+
+interface SanityImageProps {
+  value: any // SanityImageSource
+  width?: number
+  height?: number
+  className?: string
+  priority?: boolean
+}
+
+export function SanityImage({ value, width = 800, height, className, priority }: SanityImageProps) {
+  if (!value?.asset) return null
+
+  return (
+    <Image
+      className={className}
+      src={urlFor(value)
+        .width(width)
+        .height(height || Math.round(width / 1.5)) // Default aspect ratio if no height
+        .url()}
+      alt={value.alt || ''}
+      width={width}
+      height={height || Math.round(width / 1.5)}
+      priority={priority}
+      // Optional: Use LQIP (Low Quality Image Placeholder)
+      placeholder={value.asset.metadata?.lqip ? 'blur' : 'empty'}
+      blurDataURL={value.asset.metadata?.lqip}
+    />
+  )
+}
+```
+
+## 4. Querying Images
+
+**Critical:** LQIP (Low Quality Image Placeholder) is **not automatic**. You must explicitly query it via `asset->{ metadata { lqip } }`.
+
+### Minimal Query (No LQIP)
+```groq
+mainImage {
+  asset->{ _id, url },
+  alt
+}
+```
+
+### Full Query (With LQIP & Dimensions)
+```groq
+mainImage {
+  asset->{
+    _id,
+    url,
+    metadata {
+      lqip,                          // Base64 blur placeholder
+      dimensions { width, height }   // For aspect ratio
+    }
+  },
+  alt,
+  hotspot,  // Include if using hotspot cropping
+  crop      // Include if using cropping
+}
+```
+
+**Why this matters:** Without querying `metadata.lqip`, the `blurDataURL` in your component will be `undefined` and the blur effect won't work.
+
+## 5. Performance Tips
+- **Auto Format:** Sanity CDN automatically serves WebP/AVIF if the browser supports it (no need to specify `.format('webp')` manually in most cases, but `next/image` handles this too).
+- **Sizing:** Always request the exact size you need using `.width()` and `.height()` in `urlFor`. Don't download a 4000px image for a thumbnail.

+title: Sanity Localization Rules
+description: Localization patterns for Sanity using official plugins and best practices.
+---
+
+# Sanity Localization Rules
+
+Use the contents list to jump directly to the localization pattern you need.
+
+## Table of Contents
+
+- Guiding principles
+- Terminology
+- Locale content type
+- Choosing document-level vs field-level localization
+- Document-level localization
+- Localized singletons
+- Field-level localization
+- AI-powered translation
+- UI enhancement
+- Frontend URL best practices
+
+## 1. Guiding Principles
+
+### Priority: Easy Authoring Experience
+The structured nature of Sanity schemas and GROQ make it easy to parse localized content for your frontend. **Never** let frontend architecture dictate your localization approach — prioritize the editor experience.
+
+### Avoid Content Duplication
+Don't create nearly identical copies with slight differences (e.g., US vs British English). Use Portable Text marks and custom blocks to swap out words or sections as needed.
+
+## 2. Terminology
+
+| Term | Definition |
+|------|------------|
+| **Internationalization (i18n)** | Designing your frontend to support multiple languages |
+| **Localization** | Adapting content for a specific language/region |
+| **Language Tag** | Code like `en`, `en-US`, `zh-Hant-TW` (per IETF RFC 5646) |
+| **Locale** | A language tag with region info (e.g., `en-US`) |
+
+## 3. Create a Locale Content Type
+
+**Best Practice:** Store locales in Sanity, not just in code. This allows sharing between Studio and frontend.
+
+```typescript
+// schemaTypes/locale.ts
+import { TranslateIcon } from '@sanity/icons'
+import { defineField, defineType } from 'sanity'
+
+export const localeType = defineType({
+  name: 'locale',
+  icon: TranslateIcon,
+  type: 'document',
+  fields: [
+    defineField({ name: 'name', type: 'string', validation: (r) => r.required() }),
+    defineField({ name: 'tag', type: 'string', description: 'IANA tag (en, en-US)', validation: (r) => r.required() }),
+    defineField({ name: 'fallback', type: 'reference', to: [{ type: 'locale' }] }),
+    defineField({ name: 'default', type: 'boolean' }),
+  ],
+  preview: { select: { title: 'name', subtitle: 'tag' } },
+})
+```
+
+**Tip:** Restrict locale editing to admins via Structure by filtering `locale` from non-admin users.
+
+## 4. Choose Your Localization Method
+
+| Content Type | Examples | Recommended Method |
+|--------------|----------|-------------------|
+| **Structured** (things) | Products, People, Locations, Categories | Field-level |
+| **Presentation** (UI) | Pages, Posts, Components | Document-level |
+
+### Decision Questions
+1. **Are fields shared across languages?** → Field-level
+2. **Should changes be "global" for all locales?** (e.g., reordering components) → Field-level
+3. **Is content mostly the same except regional differences?** → Field-level with PT marks
+4. **Need to publish language versions independently?** → Document-level
+
+## 5. Document-Level Localization
+
+Use the **@sanity/document-internationalization** plugin.
+
+```bash
+npm install @sanity/document-internationalization
+```
+
+### Configuration
+```typescript
+// sanity.config.ts
+import { documentInternationalization } from '@sanity/document-internationalization'
+
+export default defineConfig({
+  plugins: [
+    documentInternationalization({
+      // Fetch from Content Lake
+      supportedLanguages: (client) =>
+        client.fetch(`*[_type == "locale"]{ "id": tag, "title": name }`),
+      // Document types to localize
+      schemaTypes: ['post', 'page'],
+    }),
+  ],
+})
+```
+
+### Add Language Field to Schema
+```typescript
+// In each schema type listed in schemaTypes
+defineField({
+  name: 'language',
+  type: 'string',
+  readOnly: true,
+  hidden: true,
+})
+```
+
+### Initial Value Templates
+Pre-set language when creating documents outside the translation UI:
+
+```typescript
+// sanity.config.ts
+import { template } from 'sanity'
+
+export default defineConfig({
+  // ...
+  document: {
+    newDocumentOptions: (prev, { creationContext }) => {
+      // Filter to only show base language in "New document" menu
+      // The plugin handles creating translations from there
+      return prev.filter((item) =>
+        !['post', 'page'].includes(item.templateId) ||
+        item.parameters?.language === 'en'
+      )
+    },
+  },
+  // Initial value templates for each language
+  templates: (prev) => [
+    ...prev,
+    template.initial({
+      id: 'post-en',
+      title: 'Post (English)',
+      schemaType: 'post',
+      parameters: [{name: 'language', type: 'string'}],
+      value: ({language}) => ({language}),
+    }),
+  ],
+})
+```
+
+### Querying Translated Documents
+```groq
+// Get document in specific language
+*[_type == "post" && language == $locale && slug.current == $slug][0]
+
+// Get all translations via metadata document
+*[_type == "translation.metadata" && references($docId)][0] {
+  translations[] {
+    _key,
+    value-> { title, slug, language }
+  }
+}
+```
+
+## 6. Localized Singletons (Homepage per Locale)
+
+For singletons like homepages that need a separate document per locale, combine document-level localization with the singleton pattern.
+
+### Schema Definition
+
+```typescript
+// schemaTypes/homePage.ts
+import { HomeIcon } from '@sanity/icons'
+import { defineType, defineField } from 'sanity'
+
+export const homePageType = defineType({
+  name: 'homePage',
+  title: 'Home Page',
+  type: 'document',
+  icon: HomeIcon,
+  fields: [
+    defineField({
+      name: 'language',
+      type: 'string',
+      readOnly: true,
+      hidden: true,
+    }),
+    defineField({ name: 'title', type: 'string' }),
+    defineField({ name: 'pageBuilder', type: 'pageBuilder' }),
+    // ... other fields
+  ],
+  preview: {
+    select: { language: 'language' },
+    prepare({ language }) {
+      return {
+        title: 'Home Page',
+        subtitle: language?.toUpperCase() || 'No language',
+      }
+    },
+  },
+})
+```
+
+### Initial Value Templates
+
+Create templates that pre-set the language for each locale:
+
+```typescript
+// sanity.config.ts
+import { defineConfig, Template } from 'sanity'
+
+// Define your supported locales
+const LOCALES = [
+  { id: 'en', title: 'English' },
+  { id: 'fr', title: 'French' },
+  { id: 'de', title: 'German' },
+]
+
+export default defineConfig({
+  // ...
+  templates: (prev) => {
+    // Create a template for each locale
+    const homePageTemplates: Template[] = LOCALES.map((locale) => ({
+      id: `homePage-${locale.id}`,
+      title: `Home Page (${locale.title})`,
+      schemaType: 'homePage',
+      parameters: [{ name: 'language', type: 'string' }],
+      value: { language: locale.id },
+    }))
+
+    return [...prev, ...homePageTemplates]
+  },
+})
+```
+
+### Structure: Localized Singleton Helper
+
+Create a helper to show one singleton per locale in the Structure:
+
+```typescript
+// src/structure/index.ts
+import { StructureBuilder, StructureResolver } from 'sanity/structure'
+import { HomeIcon } from '@sanity/icons'
+
+const LOCALES = ['en', 'fr', 'de']
+
+function createLocalizedSingleton(
+  S: StructureBuilder,
+  typeName: string,
+  title: string,
+  icon?: React.ComponentType
+) {
+  return S.listItem()
+    .title(title)
+    .icon(icon)
+    .child(
+      S.list()
+        .title(title)
+        .items(
+          LOCALES.map((locale) =>
+            S.listItem()
+              .title(`${title} (${locale.toUpperCase()})`)
+              .icon(icon)
+              .child(
+                S.document()
+                  .schemaType(typeName)
+                  .documentId(`${typeName}-${locale}`) // Fixed ID per locale
+                  .title(`${title} (${locale.toUpperCase()})`)
+              )
+          )
+        )
+    )
+}
+
+export const structure: StructureResolver = (S) =>
+  S.list()
+    .title('Content')
+    .items([
+      // Localized singletons
+      createLocalizedSingleton(S, 'homePage', 'Home Page', HomeIcon),
+
+      S.divider(),
+
+      // Filter localized singletons from default list
+      ...S.documentTypeListItems().filter(
+        (item) => !['homePage'].includes(item.getId() as string)
+      ),
+    ])
+```
+
+### Querying Localized Singletons
+
+```groq
+// Get homepage for specific locale
+*[_type == "homePage" && language == $locale][0]{
+  title,
+  pageBuilder[]{...}
+}
+
+// Or by fixed document ID
+*[_id == "homePage-" + $locale][0]{...}
+```
+
+### Key Points
+
+- **Fixed IDs:** Use `${typeName}-${locale}` pattern for predictable document IDs
+- **Initial Value Templates:** Essential for the "New document" menu to work correctly
+- **Structure:** Group all locale versions under one list item for cleaner navigation
+- **See also:** `studio-structure.md` for more singleton patterns
+
+## 7. Field-Level Localization
+
+Use **sanity-plugin-internationalized-array** (NOT localized objects — they hit attribute limits).
+
+```bash
+npm install sanity-plugin-internationalized-array
+```
+
+### Configuration
+```typescript
+// sanity.config.ts
+import { internationalizedArray } from 'sanity-plugin-internationalized-array'
+
+export default defineConfig({
+  plugins: [
+    internationalizedArray({
+      languages: (client) =>
+        client.fetch(`*[_type == "locale"]{ "id": tag, "title": name }`),
+      fieldTypes: ['string', 'text', 'simpleBlockContent'],
+    }),
+  ],
+})
+```
+
+### Usage in Schema
+```typescript
+// The plugin creates types like `internationalizedArrayString`
+defineField({
+  name: 'jobTitle',
+  type: 'internationalizedArrayString', // Localized string field
+})
+```
+
+### Portable Text Localization
+Create a reusable block content type, then add it to `fieldTypes`:
+
+```typescript
+// schemaTypes/simpleBlockContent.ts
+export default defineType({
+  name: 'simpleBlockContent',
+  type: 'array',
+  of: [
+    {
+      type: 'block',
+      styles: [{ title: 'Normal', value: 'normal' }],
+      lists: [],
+    },
+  ],
+})
+
+// sanity.config.ts
+fieldTypes: ['string', 'simpleBlockContent']
+
+// In your schema
+defineField({
+  name: 'bio',
+  type: 'internationalizedArraySimpleBlockContent',
+})
+```
+
+### Querying Internationalized Arrays
+```groq
+// Get specific locale value
+*[_type == "author"][0] {
+  "jobTitle": jobTitle[_key == $locale][0].value
+}
+
+// With fallback
+*[_type == "author"][0] {
+  "jobTitle": coalesce(
+    jobTitle[_key == $locale][0].value,
+    jobTitle[_key == "en"][0].value
+  )
+}
+```
+
+## 8. AI-Powered Translation
+
+Use **@sanity/assist** for automated translations.
+
+```bash
+npm install @sanity/assist
+```
+
+```typescript
+// sanity.config.ts
+import { assist } from '@sanity/assist'
+
+export default defineConfig({
+  plugins: [
+    assist({
+      translate: {
+        // For document-level localization
+        document: {
+          languageField: 'language',
+        },
+        // For field-level localization
+        field: {
+          languages: (client) =>
+            client.fetch(`*[_type == "locale"]{ "id": tag, "title": name }`),
+          documentTypes: ['author', 'category'],
+        },
+      },
+    }),
+  ],
+})
+```
+
+## 9. UI Enhancement
+
+Use **@sanity/language-filter** to let editors show/hide locales:
+
+```bash
+npm install @sanity/language-filter
+```
+
+## 10. Frontend URL Best Practices
+
+**Always include locale in the URL** for SEO:
+- `yoursite.com/en/my-page` → `yoursite.com/fr/my-page`
+- `yoursite.com/my-page` → redirects to default locale
+
+**Avoid:** Having the default locale at root without prefix — causes SEO edge cases.
+
+Use Next.js middleware (or framework equivalent) to redirect paths missing a locale prefix to the default locale.

+title: Import HTML to Portable Text
+description: Use @portabletext/block-tools with JSDOM to convert HTML content
+---
+
+## Import HTML to Portable Text
+
+Use `@portabletext/block-tools` with `JSDOM` to convert HTML from legacy CMSs to Portable Text.
+
+### Setup
+
+```bash
+npm install @portabletext/block-tools jsdom
+```
+
+### Basic Conversion
+
+```typescript
+import { htmlToBlocks } from '@portabletext/block-tools'
+import { JSDOM } from 'jsdom'
+
+// Get block content type from your schema
+const blockContentType = schema.get('blockContent')
+
+const blocks = htmlToBlocks(htmlString, blockContentType, {
+  parseHtml: html => new JSDOM(html).window.document,
+})
+```
+
+### Custom Deserializers
+
+Handle specific HTML patterns:
+
+```javascript
+const blocks = htmlToBlocks(htmlString, blockContentType, {
+  parseHtml: html => new JSDOM(html).window.document,
+  rules: [
+    {
+      deserialize(el, next, block) {
+        // Custom link handling
+        if (el.tagName.toLowerCase() === 'a') {
+          return {
+            _type: 'link',
+            href: el.getAttribute('href'),
+            blank: el.getAttribute('target') === '_blank'
+          }
+        }
+        // Custom image handling
+        if (el.tagName.toLowerCase() === 'img') {
+          return {
+            _type: 'image',
+            // Upload image separately, store reference
+            _sanityAsset: `image@${el.getAttribute('src')}`
+          }
+        }
+        return undefined  // Fall through to default handling
+      }
+    }
+  ]
+})
+```
+
+### Pre-Processing HTML
+
+Clean HTML before conversion:
+
+```javascript
+function cleanHtml(html) {
+  const dom = new JSDOM(html)
+  const doc = dom.window.document
+  
+  // Remove layout elements
+  doc.querySelectorAll('header, footer, nav, .sidebar').forEach(el => el.remove())
+  
+  // Extract metadata before processing body
+  const title = doc.querySelector('title')?.textContent
+  const description = doc.querySelector('meta[name="description"]')?.content
+  
+  return {
+    body: doc.body.innerHTML,
+    metadata: { title, description }
+  }
+}
+```
+
+### Image Upload
+
+Don't just link external images—upload them:
+
+```javascript
+async function uploadImage(client, imageUrl) {
+  const response = await fetch(imageUrl)
+  const buffer = await response.arrayBuffer()
+  
+  const asset = await client.assets.upload('image', Buffer.from(buffer), {
+    filename: imageUrl.split('/').pop()
+  })
+  
+  return {
+    _type: 'image',
+    asset: { _type: 'reference', _ref: asset._id }
+  }
+}
+```
+
+### Using in a Migration
+
+Wrap this in `defineMigration` for reproducible imports:
+
+```typescript
+// migrations/import-wordpress-posts/index.ts
+import {defineMigration, createOrReplace} from 'sanity/migrate'
+import {htmlToBlocks} from '@portabletext/block-tools'
+
+export default defineMigration({
+  title: 'Import WordPress posts',
+  async *migrate(documents, context) {
+    const posts = await fetchWordPressPosts() // Your import source
+    
+    for (const post of posts) {
+      const blocks = htmlToBlocks(post.content, blockContentType, {
+        parseHtml: html => new JSDOM(html).window.document,
+      })
+      
+      yield createOrReplace({
+        _id: `post-${post.slug}`,
+        _type: 'post',
+        title: post.title,
+        body: blocks,
+      })
+    }
+  }
+})
+```
+
+Run with: `sanity migration run import-wordpress-posts --no-dry-run`

+title: Sanity Content Migration Rules
+description: Best practices for migrating content (HTML, Markdown) into Sanity Portable Text.
+---
+
+# Sanity Content Migration Rules
+
+## 1. HTML Import (Legacy CMS)
+Use `@portabletext/block-tools` with `JSDOM` to convert HTML to Portable Text. This covers setup, custom deserializers, pre-processing, image uploads, and wrapping in `defineMigration`.
+
+**See `migration-html-import.md` for the full guide with working examples.**
+
+## 2. Markdown Import (Static Sites)
+Use `@portabletext/markdown` for direct, schema-aware Markdown ↔ Portable Text conversion.
+
+**Recommended: Direct Conversion with `@portabletext/markdown`**
+```typescript
+import {markdownToPortableText} from '@portabletext/markdown'
+
+const blocks = markdownToPortableText(markdownString)
+```
+
+This handles headings, lists, bold, italic, code, links, images, and tables. Use `@portabletext/sanity-bridge` to pass your Sanity schema so only valid types are produced.
+
+**Alternative: Markdown → HTML → Portable Text**
+For complex Markdown with non-standard extensions, convert to HTML first, then use `htmlToBlocks` (see above).
+
+1.  **Parse:** `marked` or `remark` to convert MD to HTML.
+2.  **Convert:** Use `htmlToBlocks` from `@portabletext/block-tools`.
+
+> **Note:** `@sanity/block-content-to-markdown` and `@sanity/block-tools` are deprecated. Use `@portabletext/markdown` and `@portabletext/block-tools` instead.
+
+## 3. Image Handling (Universal)
+Don't just link to external images. Download them and upload to Sanity Asset Pipeline.
+
+1.  **Extract:** Find `<img>` tags or Markdown image syntax.
+2.  **Download:** Fetch the image buffer.
+3.  **Upload:** `client.assets.upload('image', buffer)`
+4.  **Replace:** Return a Sanity Image block with the new asset reference.
+
+## 4. Schema Validation
+Ensure your destination schema allows the structures you are importing.
+-   **Tables:** Need a `table` type (HTML `<table>` or GFM tables).
+-   **Code:** Need a `code` type (HTML `<pre><code>` or MD code fences).

+Jump to the section that matches the task instead of reading this guide end-to-end.
+
+## Table of Contents
+
+- Architecture patterns
+- Data fetching (Live Content API)
+- Caching and revalidation
+- Visual Editing and clean data
+- Embedded Studio setup
+- Draft Mode setup
+- Error handling
+- Presentation queries
+- Pagination pattern
+
+## 1. Architecture Patterns
+
+### Option A: Embedded Studio (Recommended)
+**Best for:** Most Next.js projects. Unified deployment, simpler setup.
+
+The Studio lives inside your Next.js app at `/app/studio/[[...tool]]/page.tsx`.
+- **Config:** `sanity.config.ts` lives in the project root.
+- See `project-structure.md` rule for detailed structure.
+
+### Option B: Monorepo (Alternative)
+**Best for:** Separation of concerns, multiple frontends, or strict dependency isolation.
+
+The Studio and Next.js app live in separate folders:
+```
+apps/
+├── studio/     # Sanity Studio (standalone)
+└── web/        # Next.js frontend
+```
+
+- **Config:** Add your Next.js app URL to **CORS Origins** in [Sanity Manage](https://www.sanity.io/manage).
+- See `project-structure.md` rule for detailed structure.
+
+## 2. Data Fetching (Live Content API)
+
+We use `defineLive` (next-sanity v11+) to enable real-time content updates and Visual Editing automatically.
+
+### Setup (`src/sanity/lib/live.ts`)
+
+```typescript
+import { defineLive } from 'next-sanity'
+import { client } from './client'
+
+export const { sanityFetch, SanityLive } = defineLive({
+  client: client.withConfig({
+    apiVersion: '2026-02-01'
+  }),
+  serverToken: process.env.SANITY_API_READ_TOKEN,
+  browserToken: process.env.SANITY_API_READ_TOKEN,
+})
+```
+
+### Rendering (`src/app/layout.tsx`)
+
+You **must** render `<SanityLive />` in the root layout to enable real-time updates.
+
+```typescript
+import { SanityLive } from '@/sanity/lib/live'
+import { VisualEditing } from 'next-sanity/visual-editing'
+import { draftMode } from 'next/headers'
+
+export default async function RootLayout({ children }: { children: React.ReactNode }) {
+  return (
+    <html lang="en">
+      <body>
+        {children}
+        <SanityLive />
+        {(await draftMode()).isEnabled && <VisualEditing />}
+      </body>
+    </html>
+  )
+}
+```
+
+## 3. Caching & Revalidation
+
+### Prefer Live Content API (Default)
+
+**Use `defineLive` by default.** It handles fetching, caching, and invalidation automatically. Only implement manual caching when you need fine-grained control.
+
+### When to Use Manual Caching
+
+| Scenario | Approach |
+|----------|----------|
+| Real-time updates, Visual Editing | `defineLive` (default) |
+| Static marketing pages, rarely updated | Time-based revalidation |
+| Blog posts, products with frequent edits | Tag-based revalidation |
+| Critical accuracy (stock levels, prices) | Path-based + short revalidation |
+
+### Debugging: Enable Fetch Logging
+
+See every fetch with cache HIT/MISS status:
+
+```typescript
+// next.config.ts
+const nextConfig: NextConfig = {
+  logging: {
+    fetches: {
+      fullUrl: true,
+    },
+  },
+};
+```
+
+Console output shows cache status:
+```text
+GET /posts 200 in 39ms
+ │ GET https://...apicdn.sanity.io/... 200 in 5ms (cache hit)
+```
+
+### Sanity CDN vs API
+
+| Setting | Speed | Freshness | Use When |
+|---------|-------|-----------|----------|
+| `useCdn: true` | Fast | May have brief delay | Default for all runtime fetches |
+| `useCdn: false` | Slower | Guaranteed fresh | `generateStaticParams`, webhooks |
+
+Override per-request:
+```typescript
+// For static generation, use API directly
+export async function generateStaticParams() {
+  const slugs = await client
+    .withConfig({ useCdn: false })
+    .fetch(SLUGS_QUERY);
+  return slugs;
+}
+```
+
+### Manual `sanityFetch` Helper (Advanced)
+
+For manual caching control, create a wrapper:
+
+```typescript
+// src/sanity/lib/client.ts
+export async function sanityFetch<const QueryString extends string>({
+  query,
+  params = {},
+  revalidate = 60,
+  tags = [],
+}: {
+  query: QueryString;
+  params?: QueryParams;
+  revalidate?: number | false;
+  tags?: string[];
+}) {
+  return client.fetch(query, params, {
+    next: {
+      revalidate: tags.length ? false : revalidate,
+      tags,
+    },
+  });
+}
+```
+
+### Time-Based Revalidation
+
+Simple and predictable. Good for content that changes infrequently.
+
+```typescript
+const posts = await sanityFetch({
+  query: POSTS_QUERY,
+  revalidate: 3600, // Revalidate every hour
+});
+```
+
+**The "Typo Problem":** With time-based only, content authors may wait up to an hour to see changes. Use webhooks for instant updates.
+
+### Path-Based Revalidation
+
+Surgically revalidate specific routes when documents change.
+
+**1. Create API Route:**
+```typescript
+// src/app/api/revalidate/path/route.ts
+import { revalidatePath } from 'next/cache';
+import { type NextRequest, NextResponse } from 'next/server';
+import { parseBody } from 'next-sanity/webhook';
+
+type WebhookPayload = { path?: string };
+
+export async function POST(req: NextRequest) {
+  try {
+    const { isValidSignature, body } = await parseBody<WebhookPayload>(
+      req,
+      process.env.SANITY_REVALIDATE_SECRET,
+      true // Add delay to allow CDN to update
+    );
+
+    if (!isValidSignature) {
+      return new Response('Invalid signature', { status: 401 });
+    }
+    if (!body?.path) {
+      return new Response('Missing path', { status: 400 });
+    }
+
+    revalidatePath(body.path);
+    return NextResponse.json({ revalidated: body.path });
+  } catch (err) {
+    return new Response((err as Error).message, { status: 500 });
+  }
+}
+```
+
+**2. Create GROQ-Powered Webhook:**
+- URL: `https://yoursite.com/api/revalidate/path`
+- Filter: `_type in ["post"]`
+- Projection: `{ "path": "/posts/" + slug.current }`
+- Add `SANITY_REVALIDATE_SECRET` to webhook and `.env.local`
+
+### Tag-Based Revalidation
+
+"Update once, revalidate everywhere" — best for referenced content.
+
+**1. Tag Your Queries:**
+```typescript
+// Posts index - revalidate when ANY post, author, or category changes
+const posts = await sanityFetch({
+  query: POSTS_QUERY,
+  tags: ['post', 'author', 'category'],
+});
+
+// Individual post - more granular, includes slug-specific tag
+const post = await sanityFetch({
+  query: POST_QUERY,
+  params,
+  tags: [`post:${params.slug}`, 'author', 'category'],
+});
+```
+
+**2. Create API Route:**
+```typescript
+// src/app/api/revalidate/tag/route.ts
+import { revalidateTag } from 'next/cache';
+import { type NextRequest, NextResponse } from 'next/server';
+import { parseBody } from 'next-sanity/webhook';
+
+type WebhookPayload = { tags: string[] };
+
+export async function POST(req: NextRequest) {
+  try {
+    const { isValidSignature, body } = await parseBody<WebhookPayload>(
+      req,
+      process.env.SANITY_REVALIDATE_SECRET,
+      true
+    );
+
+    if (!isValidSignature) {
+      return new Response('Invalid signature', { status: 401 });
+    }
+    if (!Array.isArray(body?.tags) || !body.tags.length) {
+      return new Response('Missing tags', { status: 400 });
+    }
+
+    body.tags.forEach((tag) => revalidateTag(tag));
+    return NextResponse.json({ revalidated: body.tags });
+  } catch (err) {
+    return new Response((err as Error).message, { status: 500 });
+  }
+}
+```
+
+**3. Create GROQ-Powered Webhook:**
+- URL: `https://yoursite.com/api/revalidate/tag`
+- Filter: `_type in ["post", "author", "category"]`
+- Projection: `{ "tags": [_type, _type + ":" + slug.current] }`
+
+### Stale Data After Webhook?
+
+Webhooks fire *before* Sanity CDN updates. If you see stale data:
+
+1. **Add delay** — Pass `true` as third arg to `parseBody`
+2. **Or bypass CDN** — Set `useCdn: false` in client config (use sparingly)
+
+## 4. Visual Editing (Stega) & Clean Data
+
+Visual Editing injects invisible characters into strings to enable click-to-edit.
+
+### A. The Golden Rule of Stega
+
+If a string field controls logic (alignment, colors, IDs), you **must** clean it before comparing.
+
+```typescript
+import { stegaClean } from "@sanity/client/stega";
+
+export function Layout({ align }: { align: string }) {
+  // ❌ Bad: Will fail in Edit Mode due to invisible chars
+  // if (align === 'center') ...
+
+  // ✅ Good: Clean the value first
+  const cleanAlign = stegaClean(align);
+  return <div className={cleanAlign === 'center' ? 'mx-auto' : ''} />
+}
+```
+
+### B. Metadata & SEO (Critical)
+
+**Never** let Stega characters leak into `<head>` tags. Always set `stega: false` for metadata fetching.
+
+```typescript
+export async function generateMetadata({ params }) {
+  const { data } = await sanityFetch({
+    query: SEO_QUERY,
+    params: await params,
+    stega: false // 👈 Critical for SEO
+  })
+  return { title: data?.title }
+}
+```
+
+### C. Static Params
+
+When generating static params, fetch only published content and disable stega.
+
+```typescript
+export async function generateStaticParams() {
+  const { data } = await sanityFetch({
+    query: SLUGS_QUERY,
+    perspective: 'published', // 👈 No drafts
+    stega: false
+  })
+  return data
+}
+```
+
+## 5. Setup: Embedded Studio
+
+Mount the Studio on a Next.js route.
+
+**`src/app/studio/[[...tool]]/page.tsx`:**
+
+```typescript
+import { NextStudio } from 'next-sanity/studio'
+import config from '../../../../sanity.config'
+
+export const dynamic = 'force-static'
+export { metadata, viewport } from 'next-sanity/studio'
+
+export default function StudioPage() {
+  return <NextStudio config={config} />
+}
+```
+
+## 6. Setup: Draft Mode
+
+Enable Presentation Tool and Visual Editing by setting up a draft mode route.
+
+**`src/app/api/draft-mode/enable/route.ts`:**
+
+```typescript
+import { client } from '@/sanity/lib/client'
+import { defineEnableDraftMode } from 'next-sanity/draft-mode'
+import { token } from '@/sanity/lib/token' // Helper to get token
+
+export const { GET } = defineEnableDraftMode({
+  client: client.withConfig({ token }),
+})
+```
+
+## 7. Error Handling
+
+Use `notFound()` for missing documents. Common errors:
+
+| Error | Cause | Solution |
+|-------|-------|----------|
+| 401 Unauthorized | Invalid/missing token | Check `SANITY_API_READ_TOKEN` |
+| 403 Forbidden | CORS not configured | Add URL to CORS origins |
+| Query syntax error | Invalid GROQ | Test in Vision plugin first |
+| Empty result | Wrong filter/params | Log params, check `_type` spelling |
+
+```typescript
+import { notFound } from 'next/navigation'
+
+export default async function PostPage({ params }: Props) {
+  const { data } = await sanityFetch({ query: POST_QUERY, params: await params })
+  if (!data) notFound()
+  return <Post data={data} />
+}
+```
+
+## 8. Presentation Queries (`usePresentationQuery`)
+
+For faster live editing in the Presentation Tool, use `usePresentationQuery` to fetch only the specific block being edited, rather than re-rendering the entire page.
+
+### Why Use This
+
+- **Without:** Editing a hero title re-fetches the whole page, re-renders all blocks
+- **With:** Only the hero block re-fetches and re-renders
+
+This is especially valuable for pages with many Page Builder blocks or complex Portable Text.
+
+### Basic Pattern
+
+```typescript
+'use client'
+import { usePresentationQuery } from 'next-sanity/hooks'
+import { HERO_PRESENTATION_QUERY } from '@/sanity/lib/queries'
+
+type HeroProps = {
+  _key: string
+  documentId: string
+  title: string
+  subtitle?: string
+  // ... other initial props from page query
+}
+
+export function Hero({ _key, documentId, title, subtitle, ...rest }: HeroProps) {
+  // Fetch block-specific data for faster updates in Presentation Tool
+  const { data } = usePresentationQuery({
+    query: HERO_PRESENTATION_QUERY,
+    params: { documentId, blockKey: _key },
+  })
+
+  // Use presentation data if available, fallback to initial server props
+  const blockData = data?.heroBlock || { title, subtitle, ...rest }
+
+  return (
+    <section>
+      <h1>{blockData.title}</h1>
+      {blockData.subtitle && <p>{blockData.subtitle}</p>}
+    </section>
+  )
+}
+```
+
+### The Presentation Query
+
+Create a query that targets the specific block by `_key`:
+
+```typescript
+// queries.ts
+export const HERO_PRESENTATION_QUERY = defineQuery(`
+  *[_id == $documentId][0]{
+    _id,
+    _type,
+    "heroBlock": pageBuilder[_key == $blockKey && _type == "hero"][0]{
+      title,
+      subtitle,
+      image,
+      theme,
+      // Include all fields the component needs
+    }
+  }
+`)
+```
+
+### Passing Document Context
+
+Your PageBuilder component needs to pass `documentId` to each block:
+
+```typescript
+export function PageBuilder({ content, documentId }: { content: Block[]; documentId: string }) {
+  return (
+    <main>
+      {content.map((block) => {
+        switch (block._type) {
+          case "hero":
+            return <Hero key={block._key} documentId={documentId} {...block} />
+          // ... other blocks
+        }
+      })}
+    </main>
+  )
+}
+```
+
+### For Portable Text Blocks
+
+The same pattern works for custom blocks inside Portable Text:
+
+```typescript
+export const PTE_IMAGE_PRESENTATION_QUERY = defineQuery(`
+  *[_id == $documentId][0]{
+    "pteImageBlock": body[_key == $blockKey && _type == "pteImage"][0]{
+      image,
+      caption,
+      alt
+    }
+  }
+`)
+```
+
+**See also:** `visual-editing.md` for the conceptual overview and `page-builder.md` for full Page Builder patterns.
+
+## 9. Pagination Pattern
+
+For listing pages with many entries, use offset-based pagination with a count query.
+
+### Queries
+```typescript
+// Paginated listing
+export const ARTICLES_QUERY = defineQuery(`
+  *[_type == "article" && defined(slug.current)]
+  | order(date desc) [$start...$end] {
+    _id, title, "slug": slug.current, date
+  }
+`);
+
+// Total count for pagination UI
+export const ARTICLES_COUNT_QUERY = defineQuery(`
+  count(*[_type == "article" && defined(slug.current)])
+`);
+```
+
+### Listing Page
+```typescript
+const ENTRIES_PER_PAGE = 10;
+
+export default async function BlogPage({
+  searchParams
+}: {
+  searchParams: Promise<{ page?: string }>
+}) {
+  const { page: pageParam } = await searchParams;
+  const page = parseInt(pageParam || "1");
+  const start = (page - 1) * ENTRIES_PER_PAGE;
+  const end = start + ENTRIES_PER_PAGE;
+
+  const [{ data: articles }, { data: total }] = await Promise.all([
+    sanityFetch({ query: ARTICLES_QUERY, params: { start, end } }),
+    sanityFetch({ query: ARTICLES_COUNT_QUERY })
+  ]);
+
+  const totalPages = Math.ceil(total / ENTRIES_PER_PAGE);
+
+  return (
+    <main>
+      {articles.map(article => (
+        <ArticleCard key={article._id} article={article} />
+      ))}
+      <Pagination current={page} total={totalPages} />
+    </main>
+  );
+}
+```

+title: Nuxt & Sanity Integration Rules
+description: Integration guide for Nuxt, including @nuxtjs/sanity, visual editing, and data fetching.
+---
+
+# Nuxt & Sanity Integration Rules
+
+## 1. Setup & Configuration
+
+### Configuration (`nuxt.config.ts`)
+Use the official `@nuxtjs/sanity` module.
+
+**Important:** Ensure the `minimal` client is NOT enabled if you want full features.
+
+```typescript
+export default defineNuxtConfig({
+  modules: ["@nuxtjs/sanity"],
+  sanity: {
+    projectId: process.env.NUXT_SANITY_PROJECT_ID,
+    dataset: process.env.NUXT_SANITY_DATASET,
+    apiVersion: "2026-02-01",
+    // Live Visual Editing Configuration
+    visualEditing: {
+      studioUrl: process.env.NUXT_SANITY_STUDIO_URL,
+      token: process.env.NUXT_SANITY_API_READ_TOKEN, // Required for fetching drafts
+      stega: true, // Enable stega for visual editing
+      mode: 'live-visual-editing', // Default: enables live updates
+    },
+  },
+});
+```
+
+## 2. Data Fetching
+
+### `useSanityQuery`
+Use the composable provided by the module for reactive fetching. It automatically handles preview state when configured.
+
+```vue
+<script setup lang="ts">
+const query = groq`*[_type == "post"]{title, slug}`;
+const { data: posts } = await useSanityQuery(query);
+</script>
+
+<template>
+  <ul>
+    <li v-for="post in posts" :key="post._id">{{ post.title }}</li>
+  </ul>
+</template>
+```
+
+## 3. Visual Editing (Live Preview)
+
+### Automatic Setup
+When `visualEditing` is configured in `nuxt.config.ts`, the module handles:
+1.  Injecting the Visual Editing overlays.
+2.  Refreshing data when content changes in the Studio.
+3.  Enabling Stega encoding.
+
+### Handling Stega in Logic
+Just like Next.js, if you use stega-encoded strings in logic (e.g. `v-if="post.layout === 'full'"`), you must clean them.
+
+```typescript
+import { stegaClean } from "@sanity/client/stega";
+
+const layout = computed(() => stegaClean(props.layout));
+```
+
+## 4. Components
+
+### Portable Text
+Use the `<PortableText>` component (if installed via `@portabletext/vue` or provided by the module).
+
+```vue
+<PortableText :value="post.body" :components="customComponents" />
+```
+
+### Images
+Use `@sanity/image-url` helper or a dedicated image component.
+
+```typescript
+import imageUrlBuilder from '@sanity/image-url'
+const builder = imageUrlBuilder(useSanity().client)
+// ... url generation logic
+```

+title: "Sanity Page Builder Patterns"
+description: Patterns for Sanity Page Builder arrays, block components, and live editing.
+---
+
+# Sanity Page Builder Patterns
+
+This guide covers **Page Builder** patterns—arrays of block objects that allow content teams to compose flexible page layouts. For Portable Text (rich text within documents), see `portable-text.md`.
+
+## 1. What is a Page Builder?
+
+A page builder is an **array of objects** (`pageBuilder[]`) that allows content teams to compose pages from reusable blocks without developer intervention.
+
+**When to use:**
+- Flexible layouts needed (marketing pages, landing pages)
+- Content can be reordered
+- Different components on different pages
+
+**When NOT to use:**
+- Rigid, formulaic content (blog posts, product pages)
+- Highly structured data that doesn't change layout
+- Rich text within a document body—use Portable Text instead
+
+## 2. Schema Organization
+
+### Directory Structure
+```
+schemaTypes/
+├── blocks/           # Page builder blocks (objects)
+│   ├── heroType.ts
+│   ├── featuresType.ts
+│   └── faqsType.ts
+├── pageBuilderType.ts  # The array definition
+└── pageType.ts         # Document using the page builder
+```
+
+### Objects vs References
+
+| Use **Objects** | Use **References** |
+|-----------------|-------------------|
+| Content is unique to this page | Content reused across many pages |
+| Simpler queries | Needs central management |
+| Default choice | FAQs, CTAs, testimonials |
+
+**Rule:** Use references sparingly. Most blocks should be objects.
+
+### Page Builder Array
+```typescript
+// pageBuilderType.ts
+import { defineType, defineArrayMember } from "sanity";
+
+export const pageBuilderType = defineType({
+  name: "pageBuilder",
+  type: "array",
+  of: [
+    defineArrayMember({ type: "hero" }),
+    defineArrayMember({ type: "splitImage" }),
+    defineArrayMember({ type: "features" }),
+    defineArrayMember({ type: "faqs" }),
+  ],
+  options: {
+    insertMenu: {
+      views: [
+        // Optional: Show visual thumbnails in the insert menu grid
+        { name: "grid", previewImageUrl: (type) => `/block-previews/${type}.png` },
+      ],
+    },
+  },
+});
+```
+
+### Block Preview Pattern
+Every block should have consistent previews:
+
+```typescript
+import { defineType } from "sanity";
+import { BlockContentIcon } from "@sanity/icons";
+
+export const splitImageType = defineType({
+  name: "splitImage",
+  type: "object",
+  icon: BlockContentIcon,
+  fields: [/* ... */],
+  preview: {
+    select: { title: "title", media: "image" },
+    prepare({ title, media }) {
+      return {
+        title: title || "Untitled",
+        subtitle: "Split Image", // Block type name
+        media: media ?? BlockContentIcon, // Fallback to icon
+      };
+    },
+  },
+});
+```
+
+## 3. Querying Page Builders
+
+Expand references only for blocks that need them:
+
+```groq
+*[_type == "page" && slug.current == $slug][0]{
+  ...,
+  content[]{
+    ...,
+    _type == "faqs" => {
+      ...,
+      faqs[]->  // Expand only FAQ references
+    }
+  }
+}
+```
+
+## 4. Rendering Page Builders
+
+### TypeScript Typing
+Use `Extract` to type individual blocks from the query result:
+
+```typescript
+import { PAGE_QUERYResult } from "@/sanity/types";
+
+type HeroProps = Extract<
+  NonNullable<NonNullable<PAGE_QUERYResult>["content"]>[number],
+  { _type: "hero" }
+>;
+
+export function Hero({ title, image }: HeroProps) {
+  // Fully typed!
+}
+```
+
+### Switch-Based Rendering
+```typescript
+export function PageBuilder({ content }: { content: Block[] }) {
+  if (!Array.isArray(content)) return null;
+
+  return (
+    <main>
+      {content.map((block) => {
+        switch (block._type) {
+          case "hero":
+            return <Hero key={block._key} {...block} />;
+          case "features":
+            return <Features key={block._key} {...block} />;
+          case "splitImage":
+            return <SplitImage key={block._key} {...block} />;
+          default:
+            return <div key={block._key}>Unknown: {block._type}</div>;
+        }
+      })}
+    </main>
+  );
+}
+```
+
+**Always use `_key` for React keys:**
+```typescript
+// Breaks Visual Editing and causes hydration issues
+{items.map((item, i) => <Component key={i} {...item} />)}
+
+// Always use Sanity's _key
+{items.map((item) => <Component key={item._key} {...item} />)}
+```
+
+### Cleaning Values for Logic
+Use `stegaClean` when block fields control rendering logic:
+
+```typescript
+import { stegaClean } from "next-sanity";
+
+function SplitImage({ orientation, title, image }) {
+  return (
+    <section data-orientation={stegaClean(orientation) || "imageLeft"}>
+      {/* ... */}
+    </section>
+  );
+}
+```
+
+## 5. Presentation Queries for Live Editing (Next.js)
+
+For faster live updates in the Presentation Tool, use **presentation queries** that fetch only the specific block being edited, rather than re-fetching the entire page.
+
+> **Note:** This pattern uses `usePresentationQuery` from `next-sanity/hooks`. For other frameworks, check your loader package for equivalent functionality.
+
+### The Pattern
+
+1. **Create a block-specific presentation query:**
+
+```typescript
+// queries.ts
+export const HERO_PRESENTATION_QUERY = defineQuery(`
+  *[_id == $documentId][0]{
+    _id,
+    _type,
+    "heroBlock": pageBuilder[_key == $blockKey && _type == "hero"][0]{
+      title,
+      subtitle,
+      image,
+      // ... all fields the component needs
+    }
+  }
+`)
+```
+
+2. **Use `usePresentationQuery` in your component:**
+
+```typescript
+'use client'
+import { usePresentationQuery } from 'next-sanity/hooks'
+import { HERO_PRESENTATION_QUERY } from '@/sanity/lib/queries'
+
+type HeroProps = {
+  _key: string
+  documentId: string
+  // ... initial props from page query
+}
+
+export function Hero({ _key, documentId, ...initialProps }: HeroProps) {
+  // Fetch block-specific data for faster updates
+  const { data } = usePresentationQuery({
+    query: HERO_PRESENTATION_QUERY,
+    params: { documentId, blockKey: _key },
+  })
+
+  // Use presentation data if available, fallback to initial props
+  const blockData = data?.heroBlock || initialProps
+
+  return (
+    <section>
+      <h1>{blockData.title}</h1>
+      {/* ... */}
+    </section>
+  )
+}
+```
+
+### Why This Is Faster
+
+- **Without:** Editing a field triggers a full page re-render with all blocks
+- **With:** Only the specific block re-renders with its targeted query
+
+This pattern is especially valuable for pages with many blocks or complex nested data.
+
+**Note:** See `nextjs.md` for more details on `usePresentationQuery` and `visual-editing.md` for the conceptual overview.
+
+## 6. Page Builder Pitfalls
+
+| Pitfall | Solution |
+|---------|----------|
+| Too many block variations | Split into separate blocks if >2 variants |
+| Paradox of choice | Limit blocks per document type |
+| Overusing references | Default to objects; references only for truly shared content |
+| Unused blocks accumulate | Prune regularly; see deprecation patterns |
+| Inconsistent previews | Always set title, subtitle (block name), and media/icon |
+
+## 7. Component Alignment Pattern
+Map Sanity "alignment" fields (usually string/select) to CSS classes using utility functions.
+
+**Schema:**
+```typescript
+defineField({
+  name: 'align',
+  type: 'string',
+  options: { list: ['left', 'center', 'right'], layout: 'radio' }
+})
+```
+
+**Implementation (Utility):**
+```typescript
+import { stegaClean } from "@sanity/client/stega";
+
+export function getTextAlign(align?: string) {
+  // CLEAN the value before switching!
+  switch (stegaClean(align)) {
+    case 'left': return 'text-left';
+    case 'right': return 'text-right';
+    default: return 'text-center';
+  }
+}
+```
+
+## 8. Semantic Heading Levels
+**Rule:** Do NOT store heading levels (h1, h2) in Sanity schema options. Determine them dynamically in the frontend to ensure accessibility.
+
+**Bad Schema:**
+```typescript
+// Don't do this
+{ name: 'level', type: 'string', options: { list: ['h1', 'h2'] } }
+```
+
+**Good Component:**
+Pass a `semanticLevel` prop based on the component's context/nesting.
+
+```typescript
+type Props = {
+  block: HeroBlock;
+  level?: 'h1' | 'h2' | 'h3'; // Default to h2 if undefined
+}
+
+export default function Section({ block, level = 'h2' }: Props) {
+  const Tag = level;
+  return <Tag>{block.title}</Tag>;
+}
+```

+title: "Sanity Portable Text Rules"
+description: Portable Text (Rich Text) rendering and custom component creation for React/Next.js.
+---
+
+# Sanity Portable Text Rules
+
+Portable Text is Sanity's rich text format, used for content like article bodies (`body[]`). This guide covers rendering and creating custom PTE components.
+
+**Note:** For page-level layout blocks (`pageBuilder[]`), see `page-builder.md`.
+
+## 1. The Component
+Use the `PortableText` component from `next-sanity` (or `@portabletext/react`).
+
+```typescript
+import { PortableText } from "next-sanity";
+// or import { PortableText } from "@portabletext/react";
+
+export function Content({ value }: { value: any }) {
+  return <PortableText value={value} components={components} />;
+}
+```
+
+## 2. Custom Components (`components` prop)
+**Always** define a typed components object to handle custom blocks, marks, and list styles.
+
+```typescript
+import { PortableTextComponents } from "next-sanity";
+
+const components: PortableTextComponents = {
+  // 1. Block styles (paragraphs, headings)
+  block: {
+    h1: ({ children }) => <h1 className="text-4xl font-bold">{children}</h1>,
+    h2: ({ children }) => <h2 className="text-3xl font-bold">{children}</h2>,
+    blockquote: ({ children }) => <blockquote className="border-l-4 pl-4">{children}</blockquote>,
+  },
+
+  // 2. Custom types (non-text blocks like images, videos)
+  types: {
+    image: ({ value }) => <SanityImage value={value} />,
+    callToAction: ({ value }) => <Button href={value.url}>{value.text}</Button>,
+  },
+
+  // 3. Marks (inline decorators and annotations)
+  marks: {
+    strong: ({ children }) => <strong className="font-bold">{children}</strong>,
+    em: ({ children }) => <em className="italic">{children}</em>,
+    link: ({ children, value }) => {
+      const rel = !value.href.startsWith("/") ? "noreferrer noopener" : undefined;
+      return <a href={value.href} rel={rel} className="underline text-blue-600">{children}</a>;
+    },
+  },
+
+  // 4. Lists
+  list: {
+    bullet: ({ children }) => <ul className="list-disc ml-4">{children}</ul>,
+    number: ({ children }) => <ol className="list-decimal ml-4">{children}</ol>,
+  },
+};
+```
+
+## 3. Component Categories
+
+Portable Text has three types of custom components, each with different patterns:
+
+| Type | Examples | Pattern |
+|------|----------|---------|
+| **Block styles** | h1, h2, blockquote, normal | Text blocks with `children` prop |
+| **Custom types** | image, video, callToAction | Non-text blocks with `value` prop |
+| **Marks** | link, strong, productRef | Inline annotations wrapping text |
+
+## 4. Creating Block Style Components
+
+Block styles are text blocks like headings and paragraphs. For simple styling, inline components work fine:
+
+```typescript
+block: {
+  h2: ({ children }) => <h2 className="mt-8 mb-4 text-3xl font-bold">{children}</h2>,
+  normal: ({ children }) => <p className="mb-4 leading-relaxed">{children}</p>,
+}
+```
+
+### With Visual Editing Support
+
+For live editing in the Presentation Tool, block style components may need **both** a client and server version:
+
+```typescript
+// Heading2.tsx (Server - simple SSR for production)
+export function Heading2({ children }: { children: React.ReactNode }) {
+  return <h2 className="mt-8 mb-4 text-3xl font-bold">{children}</h2>;
+}
+
+// Heading2Client.tsx (Client - for visual editing context)
+'use client'
+export function Heading2Client({ children, value }: { children: React.ReactNode; value: any }) {
+  // Can access block data via `value` for advanced patterns
+  return <h2 className="mt-8 mb-4 text-3xl font-bold">{children}</h2>;
+}
+```
+
+Use `useIsPresentationTool` to conditionally render the client version:
+
+```typescript
+import { useIsPresentationTool } from 'next-sanity/hooks'
+
+function Heading2Wrapper(props) {
+  const isPresentationTool = useIsPresentationTool()
+
+  if (isPresentationTool) {
+    return <Heading2Client {...props} />
+  }
+  return <Heading2 {...props} />
+}
+```
+
+## 5. Creating Custom Type Components
+
+Custom types are non-text blocks like images, videos, or CTAs embedded in rich text.
+
+### Schema Definition
+
+```typescript
+// schemaTypes/blocks/pteImageBlock.ts
+import { defineType, defineField } from 'sanity'
+
+export const pteImageBlock = defineType({
+  name: 'pteImage',
+  title: 'Image',
+  type: 'object',
+  fields: [
+    defineField({ name: 'image', type: 'image', options: { hotspot: true } }),
+    defineField({ name: 'caption', type: 'string' }),
+    defineField({ name: 'alt', type: 'string', validation: (r) => r.required() }),
+  ],
+  preview: {
+    select: { title: 'caption', media: 'image' },
+  },
+})
+```
+
+### Register in Body Schema
+
+```typescript
+defineField({
+  name: 'body',
+  type: 'array',
+  of: [
+    { type: 'block' },      // Standard text
+    { type: 'pteImage' },   // Custom image block
+    { type: 'pteVideo' },   // Custom video block
+  ],
+})
+```
+
+### Frontend Component
+
+```typescript
+// PteImageComponent.tsx
+'use client'
+
+type PteImageProps = {
+  value: {
+    _key: string
+    image: any
+    caption?: string
+    alt: string
+  }
+}
+
+export function PteImageComponent({ value }: PteImageProps) {
+  if (!value.image) return null
+
+  return (
+    <figure className="my-8">
+      <SanityImage value={value.image} alt={value.alt} />
+      {value.caption && (
+        <figcaption className="text-sm text-gray-600 mt-2">{value.caption}</figcaption>
+      )}
+    </figure>
+  )
+}
+
+// Register in components
+const components: PortableTextComponents = {
+  types: {
+    pteImage: PteImageComponent,
+  },
+}
+```
+
+## 6. Creating Mark Components
+
+Marks are inline annotations that wrap text—links, highlights, or custom references.
+
+### Schema Definition (Annotation)
+
+```typescript
+// In your block configuration
+defineField({
+  name: 'body',
+  type: 'array',
+  of: [
+    {
+      type: 'block',
+      marks: {
+        decorators: [
+          { title: 'Strong', value: 'strong' },
+          { title: 'Emphasis', value: 'em' },
+          { title: 'Highlight', value: 'highlight' },
+        ],
+        annotations: [
+          {
+            name: 'link',
+            type: 'object',
+            title: 'Link',
+            fields: [
+              { name: 'href', type: 'url', title: 'URL' },
+              { name: 'openInNewTab', type: 'boolean', title: 'Open in new tab' },
+            ],
+          },
+          {
+            name: 'productRef',
+            type: 'object',
+            title: 'Product Reference',
+            fields: [
+              { name: 'product', type: 'reference', to: [{ type: 'product' }] },
+            ],
+          },
+        ],
+      },
+    },
+  ],
+})
+```
+
+### Frontend Component
+
+```typescript
+// LinkMark.tsx
+type LinkMarkProps = {
+  children: React.ReactNode
+  value: {
+    href: string
+    openInNewTab?: boolean
+  }
+}
+
+export function LinkMark({ children, value }: LinkMarkProps) {
+  const { href, openInNewTab } = value
+  const target = openInNewTab ? '_blank' : undefined
+  const rel = openInNewTab ? 'noopener noreferrer' : undefined
+
+  return (
+    <a href={href} target={target} rel={rel} className="text-blue-600 underline">
+      {children}
+    </a>
+  )
+}
+
+// Register in components
+const components: PortableTextComponents = {
+  marks: {
+    link: LinkMark,
+    highlight: ({ children }) => <mark className="bg-yellow-200">{children}</mark>,
+  },
+}
+```
+
+## 7. Presentation Queries for PTE Blocks
+
+For faster live editing of custom PTE blocks, use presentation queries that fetch only the specific block:
+
+```typescript
+// queries.ts
+export const PTE_IMAGE_PRESENTATION_QUERY = defineQuery(`
+  *[_id == $documentId][0]{
+    _id,
+    _type,
+    "pteImageBlock": body[_key == $blockKey && _type == "pteImage"][0]{
+      _key,
+      image,
+      caption,
+      alt
+    }
+  }
+`)
+```
+
+Then in your component:
+
+```typescript
+'use client'
+import { usePresentationQuery } from 'next-sanity/hooks'
+
+export function PteImageComponent({ value, documentId }: { value: any; documentId?: string }) {
+  const { data } = usePresentationQuery({
+    query: PTE_IMAGE_PRESENTATION_QUERY,
+    params: { documentId, blockKey: value._key },
+  })
+
+  const blockData = data?.pteImageBlock || value
+
+  // ... render with blockData
+}
+```
+
+**Note:** You'll need to pass `documentId` through to your PTE components. See `visual-editing.md` for context patterns.
+
+## 8. GROQ Fragment for PTE
+
+When querying documents with Portable Text, expand custom blocks:
+
+```groq
+*[_type == "article" && slug.current == $slug][0]{
+  ...,
+  body[]{
+    ...,
+    _type == "pteImage" => {
+      ...,
+      "imageUrl": image.asset->url
+    },
+    _type == "pteVideo" => {
+      ...,
+      video->{ title, url }
+    }
+  }
+}
+```
+
+## 9. Stega and Visual Editing
+
+When Visual Editing is enabled, text content contains invisible stega characters for click-to-edit functionality.
+
+**For text rendering:** Let stega characters pass through—they enable overlays:
+```typescript
+// Good - stega preserved for click-to-edit
+<h2>{children}</h2>
+```
+
+**For logic/comparisons:** Clean the values first:
+```typescript
+import { stegaClean } from '@sanity/client/stega'
+
+// Clean before using in logic
+const cleanedStyle = stegaClean(block.style)
+if (cleanedStyle === 'h2') { ... }
+```
+
+## 10. Type Safety
+When using TypeGen, the Portable Text value usually has a complex generated type. You can often use `any` or `PortableTextBlock[]` for the *prop*, but cast specific blocks if needed.
+
+```typescript
+import { PortableTextBlock } from "next-sanity";
+
+type Props = {
+  value: PortableTextBlock[];
+};
+```
+
+## 11. Best Practices
+
+- **Tailwind Typography:** For simple blogs, wrap `<PortableText />` in a `<div className="prose">` (from `@tailwindcss/typography`) instead of manually styling every block.
+- **Handling Nulls:** Always check if `value` exists and is an array before rendering.
+- **Keys:** The `PortableText` component handles React keys automatically using the `_key` from Sanity. Do not add keys manually.
+- **Separate from Page Builder:** PTE blocks live in `body[]` (rich text fields), not `pageBuilder[]` (page layout). Keep these patterns separate.

+
+# Sanity Project Structure
+
+## Standalone Studio
+
+Best for content-only projects, API-first architectures, or when frontend is managed separately.
+
+```
+your-project/
+├── schemaTypes/
+│   ├── index.ts
+│   ├── documents/
+│   ├── objects/
+│   └── blocks/

+└── package.json
+```
+
+**Use cases:**
+- Content modeling with MCP/AI tools (no frontend needed)
+- Headless CMS with external consumers
+- Prototyping and content design
+
+## Embedded Studio (Recommended for Next.js)
+
+Best for most Next.js projects. Unified deployment, simpler setup.
+
+```

+```
+
+## Monorepo
+
+Best when you need separation of concerns, multiple frontends, or strict dependency isolation.
+
+```

+```
+
+**Setup:**
+1. Add web app URL to CORS origins in [Sanity Manage](https://www.sanity.io/manage)
+2. Configure `typegen` in `sanity.cli.ts` to read schema from `apps/studio` and output types to `apps/web`
+
+## File Naming Conventions
+
+- **kebab-case** for all files: `user-profile.ts`, `hero-block.ts`
+- `.ts` for schemas/utilities, `.tsx` for React components
+- Each schema exports a named const matching filename
+
+## Schema Directory Structure
+
+```

+title: React Router (Remix) & Sanity Integration Rules
+description: Integration guide for React Router (formerly Remix) with Sanity, including Loaders and Visual Editing.
+---
+
+# React Router (Remix) & Sanity Integration Rules
+
+## Version Note
+
+This guide covers both:
+- **Remix v2** (`@remix-run/*` packages)
+- **React Router v7** (the successor to Remix, `react-router` package)
+
+The Sanity integration pattern is the same for both. Import paths differ slightly:
+
+| Remix v2 | React Router v7 |
+|----------|-----------------|
+| `@remix-run/node` | `react-router` |
+| `@remix-run/react` | `react-router` |
+| `remix.config.js` | `react-router.config.ts` |
+
+The examples below use Remix v2 imports. Adjust if using React Router v7.
+
+## 1. Setup & Client Pattern
+
+To support both server-side fetching and client-side live previews, use the **Split Loader Pattern**.
+
+### A. Shared Loader (`app/sanity/loader.ts`)
+Defines the store config (SSR enabled, client deferred).
+
+```typescript
+import { createQueryStore } from '@sanity/react-loader'
+
+export const {
+  loadQuery,
+  setServerClient,
+  useQuery,
+  useLiveMode,
+} = createQueryStore({ client: false, ssr: true })
+```
+
+### B. Server Loader (`app/sanity/loader.server.ts`)
+Initializes the server client.
+
+```typescript
+import { createClient } from '@sanity/client'
+import { loadQuery, setServerClient } from './loader'
+
+const client = createClient({
+  projectId: process.env.SANITY_PROJECT_ID,
+  dataset: process.env.SANITY_DATASET,
+  useCdn: true,
+  apiVersion: '2026-02-01',
+  stega: {
+    enabled: true,
+    studioUrl: 'https://my-studio-url.com',
+  },
+})
+
+setServerClient(client)
+
+export { loadQuery }
+```
+
+## 2. Data Fetching (Loaders)
+
+Use `loadQuery` from your **server** file in route loaders.
+
+```typescript
+import type { LoaderFunctionArgs } from "@remix-run/node";
+import { useLoaderData } from "@remix-run/react";
+import { loadQuery } from "~/sanity/loader.server";
+import { POSTS_QUERY } from "~/sanity/queries";
+
+export async function loader({ params }: LoaderFunctionArgs) {
+  const initial = await loadQuery(POSTS_QUERY, params);
+  return { initial, query: POSTS_QUERY, params };
+}
+
+export default function Index() {
+  const { initial, query, params } = useLoaderData<typeof loader>();
+  // ... pass to component
+}
+```
+
+## 3. Real-time Preview & Visual Editing
+
+### A. Use `useQuery` in Components
+Import `useQuery` from your **shared** loader file.
+
+```typescript
+import { useQuery } from "~/sanity/loader";
+
+export default function Page() {
+  const { initial, query, params } = useLoaderData<typeof loader>();
+
+  const { data, encodeDataAttribute } = useQuery(query, params, {
+    initial
+  });
+
+  return (
+    <h1 data-sanity={encodeDataAttribute('title')}>
+      {data?.title}
+    </h1>
+  );
+}
+```
+
+### B. Enable Live Mode (`VisualEditing.tsx`)
+Create a component to handle the connection.
+
+```typescript
+import { enableVisualEditing } from '@sanity/visual-editing'
+import { useLiveMode } from '~/sanity/loader'
+import { client } from '~/sanity/client' // Your browser-safe client
+import { useEffect } from 'react'
+
+export default function VisualEditing() {
+  useEffect(() => enableVisualEditing(), [])
+  useLiveMode({ client })
+  return null
+}
+```
+
+Render this component in `root.tsx` only when valid (e.g., check env vars or user session).
+
+## 4. Stega Cleaning
+When using data for logic (routing, classNames), use `stegaClean`.
+
+```typescript
+import { stegaClean } from "@sanity/client/stega"
+// ...
+if (stegaClean(slug) === 'home') { ... }
+```

+title: Sanity Schema Best Practices
+description: Rules for defining Sanity Content Models (Schemas), including field definitions, strict typing, and validation patterns.
+---
+
+# Sanity Schema Best Practices
+
+Use this contents list to jump to the schema design decision you are making.
+
+## Table of Contents
+
+- Core philosophy: data over presentation
+- Strict definition syntax
+- Shared fields pattern
+- Field patterns
+- References vs nested objects
+- Safe schema updates
+- Validation patterns
+
+## 1. Core Philosophy: Data > Presentation
+Model **what things are**, not **what they look like**.
+- ❌ **Bad:** `bigHeroText`, `redButton`, `threeColumnRow`, `color`, `fontSize`
+- ✅ **Good:** `heroStatement`, `callToAction`, `featuresSection`, `status`, `role`
+
+**The test:** "If we redesigned the site, would this field name still make sense?"
+- `threeColumnLayout` → ❌ Fails (what if we go to 2 columns?)
+- `features` → ✅ Passes (features are features regardless of layout)
+
+## 2. Strict Definition Syntax
+Always use the helper functions from `sanity` for type safety and autocompletion.
+
+- **ALWAYS** use `defineType` for the root export.
+- **ALWAYS** use `defineField` for fields.
+- **ALWAYS** use `defineArrayMember` for items inside arrays.
+
+```typescript
+import { defineType, defineField, defineArrayMember } from 'sanity'
+import { TagIcon } from '@sanity/icons'
+
+export const article = defineType({
+  name: 'article',
+  title: 'Article',
+  type: 'document',
+  icon: TagIcon,
+  fields: [
+    defineField({
+      name: 'title',
+      type: 'string',
+      validation: (rule) => rule.required(),
+    }),
+    defineField({
+      name: 'tags',
+      type: 'array',
+      of: [
+        // ALWAYS use defineArrayMember for array items
+        defineArrayMember({ type: 'reference', to: [{ type: 'tag' }] })
+      ]
+    })
+  ]
+})
+```
+
+## 3. Shared Fields Pattern
+Export arrays of fields to reuse common patterns (e.g., SEO, standard page headers).
+
+```typescript
+// src/schemaTypes/shared/seoFields.ts
+export const seoFields = [
+  defineField({ name: 'seoTitle', type: 'string', title: 'SEO Title' }),
+  defineField({ name: 'seoDesc', type: 'text', title: 'SEO Description' })
+]
+
+// Usage
+defineType({
+  name: 'page',
+  fields: [
+    defineField({ name: 'title', type: 'string' }),
+    ...seoFields // Spread shared fields
+  ]
+})
+```
+
+## 4. Field Patterns
+
+### A. Array Keys (`_key`)
+Every item in a Sanity array automatically gets a `_key` property. This is **critical** for:
+- React reconciliation (use as `key` prop)
+- Visual Editing overlays (click-to-edit)
+- Portable Text rendering
+
+**Schema:** Sanity auto-generates `_key` for array items. You don't define it.
+
+**Frontend:** Always use `_key` as React's `key`:
+```typescript
+// ✅ Correct
+{items.map((item) => <Component key={item._key} {...item} />)}
+
+// ❌ Wrong - index keys break Visual Editing
+{items.map((item, i) => <Component key={i} {...item} />)}
+```
+
+**Querying:** Always include `_key` in array projections:
+```groq
+*[_type == "page"][0]{
+  pageBuilder[]{
+    _key,  // Always include _key in queries
+    _type,
+    ...
+  }
+}
+```
+
+### B. Icons
+Always assign an icon from `@sanity/icons` to documents and objects. This improves the Studio UX significantly. Browse all icons at [icons.sanity.build](https://icons.sanity.build/all).
+
+| Content Type | Icon |
+|--------------|------|
+| Article, Post | `DocumentTextIcon` |
+| Author, Person | `UserIcon` |
+| Category, Tag | `TagIcon` |
+| Settings | `CogIcon` |
+| Page | `DocumentIcon` |
+| Image block | `ImageIcon` |
+| Video block | `PlayIcon` |
+| FAQ | `HelpCircleIcon` |
+| Link | `LinkIcon` |
+
+### C. Boolean vs. List
+Avoid boolean fields for binary states that might expand later.
+- **Prefer:** `options.list` with "radio" layout.
+
+```typescript
+defineField({
+  name: 'status',
+  type: 'string',
+  options: {
+    list: [
+      { title: 'Draft', value: 'draft' },
+      { title: 'Published', value: 'published' }
+    ],
+    layout: 'radio'
+  }
+})
+```
+
+### D. The "Toggle" Pattern (Conditional Fields)
+Use a radio/boolean field to toggle visibility of other fields (often grouped in fieldsets).
+
+```typescript
+defineField({
+  name: 'linkType',
+  type: 'string',
+  options: { list: ['internal', 'external'], layout: 'radio' }
+}),
+defineField({
+  name: 'internalLink',
+  type: 'reference',
+  hidden: ({ parent }) => parent?.linkType !== 'internal'
+}),
+defineField({
+  name: 'externalUrl',
+  type: 'url',
+  hidden: ({ parent }) => parent?.linkType !== 'external'
+})
+```
+
+## 5. References vs Nested Objects
+
+A **critical modeling decision**: when to use `reference` vs embedding an `object`.
+
+### Use References When:
+- Content is **reusable** across documents (authors, categories, products)
+- Content needs its **own editing interface** in Studio
+- You need to query/filter by the related content independently
+- Multiple documents should share the **same instance** (update once, reflect everywhere)
+
+```typescript
+// ✅ Author is reusable and independently editable
+defineField({
+  name: 'author',
+  type: 'reference',
+  to: [{ type: 'author' }]
+})
+```
+
+### Use Nested Objects When:
+- Content is **specific to this document** (not shared)
+- Content doesn't make sense on its own (address, SEO metadata)
+- You want **simpler editing** (all fields in one place)
+- You need the data to be **copied** not linked
+
+```typescript
+// ✅ SEO is document-specific, not shared
+defineField({
+  name: 'seo',
+  type: 'object',
+  fields: [
+    defineField({ name: 'title', type: 'string' }),
+    defineField({ name: 'description', type: 'text' })
+  ]
+})
+```
+
+### Quick Decision Matrix
+
+| Scenario | Use |
+|----------|-----|
+| Blog post author | `reference` (reusable) |
+| Product category | `reference` (shared taxonomy) |
+| Page SEO fields | `object` (page-specific) |
+| Hero section content | `object` (page-specific) |
+| Team member on About page | `reference` (might be used elsewhere) |
+| Call-to-action button | `object` (usually page-specific) |
+
+### Querying Differences
+```groq
+// Reference requires expansion
+*[_type == "post"]{ author->{ name, bio } }
+
+// Object is already inline
+*[_type == "post"]{ seo { title, description } }
+```
+
+## 6. Safe Schema Updates (The Deprecation Pattern)
+
+**NEVER** delete a field that contains production data. It will cause data loss or Studio crashes. Instead, follow the **ReadOnly -> Hidden -> Deprecated** lifecycle.
+
+### The Pattern
+1.  **`deprecated`**: Adds a visual warning and reason.
+2.  **`readOnly: true`**: Prevents new edits but keeps data visible.
+3.  **`hidden`**: Hides it from *new* documents (where value is undefined).
+4.  **`initialValue: undefined`**: Ensures new documents don't get this field.
+
+```typescript
+defineField({
+  name: 'oldTitle', // The field you want to remove
+  title: 'Article Title (Deprecated)',
+  type: 'string',
+  deprecated: {
+    reason: 'Use the new "seoTitle" field instead. This will be removed in v2.'
+  },
+  readOnly: true,
+  hidden: ({ value }) => value === undefined,
+  initialValue: undefined
+})
+```
+
+### Migration Workflow
+
+**Phase 1: Deprecate** — Apply the deprecation pattern above. Deploy.
+
+**Phase 2: Migrate** — Update frontend to use new fields (with `coalesce()` fallbacks). Create a migration:
+
+```typescript
+// migrations/rename-oldTitle-to-newTitle/index.ts
+import {defineMigration, at, setIfMissing, unset} from 'sanity/migrate'
+
+export default defineMigration({
+  title: 'Rename oldTitle to newTitle',
+  documentTypes: ['article'],
+  filter: 'defined(oldTitle) && !defined(newTitle)',
+  migrate: {
+    document(doc) {
+      if (!doc.oldTitle || doc.newTitle) return
+      return [
+        at('newTitle', setIfMissing(doc.oldTitle)),
+        at('oldTitle', unset())
+      ]
+    }
+  }
+})
+```
+
+```bash
+# Dry run first (default)
+sanity migration run rename-oldTitle-to-newTitle
+
+# Execute when ready
+sanity migration run rename-oldTitle-to-newTitle --no-dry-run
+```
+
+**Phase 3: Remove** — Once `oldTitle` is undefined for all documents, delete the field definition.
+
+## 7. Validation Patterns
+
+Beyond `rule.required()`, Sanity offers powerful validation options.
+
+### Common Patterns
+
+```typescript
+// Email validation
+defineField({
+  name: 'email',
+  type: 'string',
+  validation: (rule) => rule.email().required()
+})
+
+// URL validation (with custom message)
+defineField({
+  name: 'website',
+  type: 'url',
+  validation: (rule) => rule.uri({
+    scheme: ['http', 'https']
+  }).error('Must be a valid URL starting with http:// or https://')
+})
+
+// Length constraints
+defineField({
+  name: 'excerpt',
+  type: 'text',
+  validation: (rule) => rule.max(200).warning('Keep it under 200 characters for best SEO')
+})
+
+// Regex pattern
+defineField({
+  name: 'slug',
+  type: 'slug',
+  validation: (rule) => rule.required().custom((slug) => {
+    if (!slug?.current) return 'Required'
+    if (!/^[a-z0-9-]+$/.test(slug.current)) {
+      return 'Slug must be lowercase with hyphens only'
+    }
+    return true
+  })
+})
+```
+
+### Cross-Field Validation
+
+```typescript
+defineField({
+  name: 'endDate',
+  type: 'datetime',
+  validation: (rule) => rule.custom((endDate, context) => {
+    const startDate = context.document?.startDate
+    if (startDate && endDate && new Date(endDate) < new Date(startDate)) {
+      return 'End date must be after start date'
+    }
+    return true
+  })
+})
+```
+
+### Array Validation
+
+```typescript
+defineField({
+  name: 'tags',
+  type: 'array',
+  of: [{ type: 'string' }],
+  validation: (rule) => rule
+    .min(1).error('Add at least one tag')
+    .max(10).warning('Too many tags may hurt SEO')
+    .unique()
+})
+```
+
+### Async Validation (Uniqueness Check)
+
+```typescript
+defineField({
+  name: 'slug',
+  type: 'slug',
+  validation: (rule) => rule.required().custom(async (slug, context) => {
+    if (!slug?.current) return true
+
+    const client = context.getClient({ apiVersion: '2026-02-01' })
+    const id = context.document?._id?.replace(/^drafts\./, '')
+
+    const existing = await client.fetch(
+      `count(*[_type == "post" && slug.current == $slug && _id != $id])`,
+      { slug: slug.current, id }
+    )
+
+    return existing === 0 || 'Slug already exists'
+  })
+})
+```

+title: Sanity SEO Best Practices
+description: SEO best practices for Sanity with Next.js, including metadata, Open Graph, sitemaps, redirects, and JSON-LD structured data.
+---
+
+# Sanity SEO Best Practices
+
+## 1. Core Philosophy
+
+SEO doesn't require complex configurations. A few core principles, applied consistently:
+
+- **Smart defaults with optional overrides** — Don't require SEO fields; use existing content as fallback
+- **Use GROQ for fallback logic** — Move conditional logic into queries, not components
+- **Leverage Next.js APIs** — Use `generateMetadata`, `sitemap.ts`, not manual `<meta>` tags
+- **Structured content = structured data** — Your content model is already SEO-ready
+
+## 2. SEO Schema Type (Reusable)
+
+Create a reusable SEO object type for consistent metadata across document types.
+
+```typescript
+// schemaTypes/seoType.ts
+import { defineField, defineType } from "sanity";
+
+export const seoType = defineType({
+  name: "seo",
+  title: "SEO",
+  type: "object",
+  fields: [
+    defineField({
+      name: "title",
+      description: "Overrides the page title if provided",
+      type: "string",
+    }),
+    defineField({
+      name: "description",
+      type: "text",
+      rows: 3,
+    }),
+    defineField({
+      name: "image",
+      description: "Image for social sharing (1200x630 recommended)",
+      type: "image",
+      options: { hotspot: true },
+    }),
+    defineField({
+      name: "noIndex",
+      description: "Hide this page from search engines",
+      type: "boolean",
+      initialValue: false,
+    }),
+  ],
+});
+```
+
+**Usage in document types:**
+```typescript
+defineField({
+  name: "seo",
+  type: "seo",
+})
+```
+
+## 3. GROQ Queries with Fallbacks
+
+Use `coalesce()` to provide fallback values. This keeps frontend logic clean.
+
+```groq
+*[_type == "page" && slug.current == $slug][0]{
+  ...,
+  "seo": {
+    // Use SEO field if provided, otherwise fall back to main title
+    "title": coalesce(seo.title, title, ""),
+    "description": coalesce(seo.description, ""),
+    "image": seo.image,
+    "noIndex": seo.noIndex == true
+  }
+}
+```
+
+**Key principle:** `seo.title` will never be `null` — it contains either the SEO override, the page title, or empty string.
+
+## 4. Next.js Metadata (The Right Way)
+
+Use `generateMetadata` — never render `<title>` or `<meta>` tags directly in components.
+
+```typescript
+// app/(frontend)/[slug]/page.tsx
+import type { Metadata } from "next";
+import { urlFor } from "@/sanity/lib/image";
+
+type RouteProps = {
+  params: Promise<{ slug: string }>;
+};
+
+// Extract fetch to reuse in both functions
+const getPage = async (params: RouteProps["params"]) =>
+  sanityFetch({
+    query: PAGE_QUERY,
+    params: await params,
+    stega: false, // Critical for SEO!
+  });
+
+export async function generateMetadata({ params }: RouteProps): Promise<Metadata> {
+  const { data: page } = await getPage(params);
+
+  if (!page) return {};
+
+  const metadata: Metadata = {
+    title: page.seo.title,
+    description: page.seo.description,
+  };
+
+  // Open Graph image
+  if (page.seo.image) {
+    metadata.openGraph = {
+      images: {
+        url: urlFor(page.seo.image).width(1200).height(630).url(),
+        width: 1200,
+        height: 630,
+      },
+    };
+  }
+
+  // noIndex robots directive
+  if (page.seo.noIndex) {
+    metadata.robots = "noindex";
+  }
+
+  return metadata;
+}
+
+export default async function Page({ params }: RouteProps) {
+  const { data: page } = await getPage(params);
+  // ... render page
+}
+```
+
+**Critical:** Always set `stega: false` when fetching for metadata. Stega characters in `<title>` destroy SEO.
+
+## 5. Dynamic Sitemap
+
+Use Next.js `sitemap.ts` convention to auto-generate from Sanity content.
+
+### GROQ Query
+```groq
+*[_type in ["page", "post"] && defined(slug.current) && seo.noIndex != true] {
+  "href": select(
+    _type == "page" => "/" + slug.current,
+    _type == "post" => "/posts/" + slug.current,
+    slug.current
+  ),
+  _updatedAt
+}
+```
+
+### Route Implementation
+```typescript
+// app/sitemap.ts
+import { MetadataRoute } from "next";
+import { client } from "@/sanity/lib/client";
+import { SITEMAP_QUERY } from "@/sanity/lib/queries";
+
+export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
+  const baseUrl = process.env.VERCEL_URL
+    ? `https://${process.env.VERCEL_URL}`
+    : "http://localhost:3000";
+
+  try {
+    const paths = await client.fetch(SITEMAP_QUERY);
+    if (!paths) return [];
+
+    return paths.map((path) => ({
+      url: new URL(path.href!, baseUrl).toString(),
+      lastModified: new Date(path._updatedAt),
+      changeFrequency: "weekly",
+      priority: 1,
+    }));
+  } catch (error) {
+    console.error("Sitemap generation failed:", error);
+    return [];
+  }
+}
+```
+
+**Note:** Sitemap limit is 50,000 URLs per file. For larger sites, use sitemap index.
+
+## 6. Redirects (Managed in Sanity)
+
+Create a redirect document type for content team management.
+
+### Schema
+```typescript
+// schemaTypes/redirectType.ts
+import { defineField, defineType, SanityDocumentLike } from "sanity";
+import { LinkIcon } from "@sanity/icons";
+
+function isValidPath(value: string | undefined) {
+  if (!value) return "Required";
+  if (!value.startsWith("/")) return "Must start with /";
+  if (/[^a-zA-Z0-9\-_/:]/.test(value)) return "Invalid characters";
+  return true;
+}
+
+export const redirectType = defineType({
+  name: "redirect",
+  title: "Redirect",
+  type: "document",
+  icon: LinkIcon,
+  validation: (Rule) =>
+    Rule.custom((doc: SanityDocumentLike | undefined) => {
+      if (doc?.source === doc?.destination) {
+        return "Source and destination cannot be the same";
+      }
+      return true;
+    }),
+  fields: [
+    defineField({
+      name: "source",
+      type: "string",
+      validation: (Rule) => Rule.required().custom(isValidPath),
+    }),
+    defineField({
+      name: "destination",
+      type: "string",
+      validation: (Rule) => Rule.required(),
+    }),
+    defineField({
+      name: "permanent",
+      description: "301 (permanent) or 302 (temporary)",
+      type: "boolean",
+      initialValue: true,
+    }),
+    defineField({
+      name: "isEnabled",
+      type: "boolean",
+      initialValue: true,
+    }),
+  ],
+});
+```
+
+### Next.js Config
+```typescript
+// next.config.ts
+import { fetchRedirects } from "@/sanity/lib/fetchRedirects";
+
+const nextConfig: NextConfig = {
+  async redirects() {
+    return await fetchRedirects();
+  },
+};
+```
+
+**Limits:** Vercel allows max 1,024 redirects in `next.config`. For more, use middleware.
+
+## 7. Dynamic Open Graph Images
+
+Generate OG images on-the-fly using Next.js Edge Runtime at `/api/og`.
+
+```typescript
+// app/api/og/route.tsx
+import { ImageResponse } from "next/og";
+export const runtime = "edge";
+
+export async function GET(request: Request) {
+  const id = new URL(request.url).searchParams.get("id");
+  if (!id) return new Response("Missing id", { status: 400 });
+
+  const data = await client.fetch(`*[_id == $id][0]{ title }`, { id });
+
+  return new ImageResponse(
+    <div tw="flex w-full h-full bg-blue-500 text-white p-10">
+      <h1 tw="text-6xl font-bold">{data?.title || "Untitled"}</h1>
+    </div>,
+    { width: 1200, height: 630 }
+  );
+}
+```
+
+Use as fallback in metadata: `url: page.seo.image ? urlFor(page.seo.image).url() : \`/api/og?id=\${page._id}\``
+
+## 8. JSON-LD Structured Data
+
+Use `schema-dts` for type-safe structured data.
+
+```bash
+npm install schema-dts
+```
+
+### FAQ Example
+```typescript
+import { FAQPage, WithContext } from "schema-dts";
+
+const generateFaqData = (faqs: FAQ[]): WithContext<FAQPage> => ({
+  "@context": "https://schema.org",
+  "@type": "FAQPage",
+  mainEntity: faqs.map((faq) => ({
+    "@type": "Question",
+    name: faq.title,
+    acceptedAnswer: {
+      "@type": "Answer",
+      text: faq.text, // Use pt::text() in GROQ to get plain text
+    },
+  })),
+});
+
+// In component
+<script
+  type="application/ld+json"
+  dangerouslySetInnerHTML={{ __html: JSON.stringify(generateFaqData(faqs)) }}
+/>
+```
+
+### GROQ for Plain Text
+```groq
+faqs[]->{
+  _id,
+  title,
+  body,
+  "text": pt::text(body)  // Convert Portable Text to plain string
+}
+```

+title: "Sanity Studio Structure Rules"
+description: Rules for customizing the Sanity Studio Structure (S.structure).
+---
+
+# Sanity Studio Structure Rules
+
+## 1. Setup
+Custom structure is defined in `sanity.config.ts` using the `structureTool`.
+
+```typescript
+import { structureTool } from 'sanity/structure'
+import { structure } from './src/structure'
+
+export default defineConfig({
+  // ...
+  plugins: [
+    structureTool({ structure })
+  ]
+})
+```
+
+## 2. Structure Definition
+**Location:** `src/structure/index.ts`
+
+Use a function that receives `S` (StructureBuilder).
+
+```typescript
+import type { StructureResolver } from 'sanity/structure'
+
+export const structure: StructureResolver = (S) =>
+  S.list()
+    .title('Content')
+    .items([
+      // ... items
+    ])
+```
+
+## 3. Organization Principles
+1.  **Singletons First:** Place critical site-wide settings (Global Settings, Homepage) at the top.
+2.  **Dividers:** Use `S.divider()` to visually separate logical groups.
+3.  **Filtered Lists:** Always exclude Singleton documents from generic `documentTypeList` items to avoid duplication.
+
+## 4. Singleton Pattern (Critical)
+
+**Singletons are enforced via Structure, NOT schema options.** There is no `singleton: true` schema option.
+
+### How Singletons Work
+1. Use `S.document().documentId('fixed-id')` to lock the document to a specific ID.
+2. Filter the type from generic lists to prevent duplicate entries.
+
+### Singleton Helper Function
+```typescript
+// Helper to create singleton list items
+function createSingleton(S: StructureBuilder, typeName: string, title: string, icon?: ComponentType) {
+  return S.listItem()
+    .title(title)
+    .icon(icon)
+    .child(
+      S.document()
+        .schemaType(typeName)
+        .documentId(typeName) // Fixed ID = singleton
+        .title(title)
+    )
+}
+
+// Usage
+createSingleton(S, 'settings', 'Site Settings', CogIcon)
+```
+
+### Querying Singletons
+```groq
+// By fixed ID (most efficient)
+*[_id == "settings"][0]
+
+// By type (works but slower)
+*[_type == "settings"][0]
+```
+
+**For localized singletons** (e.g., homepage per language), see `localization.md` Section 6.
+
+## 5. Implementation Pattern
+
+```typescript
+// Define singleton types to exclude from generic lists
+const SINGLETONS = ['settings', 'homePage']
+
+export const structure: StructureResolver = (S) =>
+  S.list()
+    .title('Website Content')
+    .items([
+      // 1. Singletons
+      S.listItem()
+        .title('Site Settings')
+        .icon(CogIcon)
+        .child(S.document().schemaType('settings').documentId('settings')),
+
+      S.divider(),
+
+      // 2. Content Verticals
+      S.listItem()
+        .title('Blog')
+        .child(
+          S.list()
+            .title('Blog Content')
+            .items([
+              S.documentTypeListItem('post').title('Posts'),
+              S.documentTypeListItem('author').title('Authors'),
+            ])
+        ),
+
+      S.divider(),
+
+      // 3. Remaining Documents (Filtered)
+      ...S.documentTypeListItems().filter(
+        (listItem) => !SINGLETONS.includes(listItem.getId() as string)
+      )
+    ])
+```
+
+## 6. Views (Split Pane)
+Add "Web Preview" or other views to documents.
+
+```typescript
+export const defaultDocumentNode: DefaultDocumentNodeResolver = (S, { schemaType }) => {
+  switch (schemaType) {
+    case `post`:
+      return S.document().views([
+        S.view.form(), // Default form
+        S.view.component(PreviewComponent).title('Preview') // Custom view
+      ])
+    default:
+      return S.document().views([S.view.form()])
+  }
+}
+```

+title: "SvelteKit & Sanity Integration Rules"
+description: Integration guide for SvelteKit with Sanity, including @sanity/svelte-loader, Visual Editing, and Preview Mode.
+---
+
+# SvelteKit & Sanity Integration Rules
+
+## 1. Setup & Configuration
+
+### Installation
+```bash
+npm install @sanity/svelte-loader @sanity/client @sanity/visual-editing
+```
+
+### Client Configuration (`src/lib/sanity.ts`)
+Define the client with `stega` enabled for the studio URL.
+
+```typescript
+import { createClient } from '@sanity/client'
+import { PUBLIC_SANITY_PROJECT_ID, PUBLIC_SANITY_DATASET, PUBLIC_SANITY_API_VERSION, PUBLIC_SANITY_STUDIO_URL } from '$env/static/public'
+
+export const client = createClient({
+  projectId: PUBLIC_SANITY_PROJECT_ID,
+  dataset: PUBLIC_SANITY_DATASET,
+  apiVersion: PUBLIC_SANITY_API_VERSION,
+  useCdn: true,
+  stega: {
+    studioUrl: PUBLIC_SANITY_STUDIO_URL,
+  },
+})
+```
+
+### Server Client (`src/lib/server/sanity.ts`)
+Use the read token for fetching preview content.
+
+```typescript
+import { SANITY_API_READ_TOKEN } from '$env/static/private'
+import { client } from '$lib/sanity'
+
+export const serverClient = client.withConfig({
+  token: SANITY_API_READ_TOKEN,
+  stega: true, // Optional: enable stega on server too if needed
+})
+```
+
+## 2. Hooks & Request Handler (Critical)
+
+You **must** configure `createRequestHandler` in `src/hooks.server.ts` to handle preview sessions and inject `loadQuery` into locals.
+
+```typescript
+// src/hooks.server.ts
+import { createRequestHandler, setServerClient } from '@sanity/svelte-loader'
+import { serverClient } from '$lib/server/sanity'
+
+setServerClient(serverClient)
+
+export const handle = createRequestHandler()
+```
+
+**Update `app.d.ts` types:**
+```typescript
+import type { LoaderLocals } from '@sanity/svelte-loader'
+
+declare global {
+  namespace App {
+    interface Locals extends LoaderLocals {}
+  }
+}
+```
+
+## 3. Preview State Propagation
+
+Pass the preview state from the server to the client via the root layout.
+
+**Server Layout (`src/routes/+layout.server.ts`):**
+```typescript
+import type { LayoutServerLoad } from './$types'
+
+export const load: LayoutServerLoad = ({ locals: { preview } }) => {
+  return { preview }
+}
+```
+
+**Client Layout (`src/routes/+layout.ts`):**
+```typescript
+import { setPreviewing } from '@sanity/svelte-loader'
+import type { LayoutLoad } from './$types'
+
+export const load: LayoutLoad = ({ data: { preview } }) => {
+  setPreviewing(preview)
+}
+```
+
+## 4. Data Fetching (Loaders)
+
+Use `locals.loadQuery` in your page server loaders.
+
+```typescript
+// src/routes/[slug]/+page.server.ts
+import type { PageServerLoad } from './$types'
+
+export const load: PageServerLoad = async ({ locals: { loadQuery }, params }) => {
+  const initial = await loadQuery(QUERY, params)
+  return { initial }
+}
+```
+
+## 5. Real-time Preview & Visual Editing
+
+### Component Usage (`useQuery`)
+Use `useQuery` in your Svelte component to handle real-time updates.
+
+```svelte
+<!-- src/routes/[slug]/+page.svelte -->
+<script lang="ts">
+  import { useQuery } from '@sanity/svelte-loader'
+  import type { PageData } from './$types'
+
+  export let data: PageData
+  const { initial } = data
+
+  // Hydrate with initial data
+  const query = useQuery(initial)
+
+  // Reactive data access
+  $: ({ data: post, loading, encodeDataAttribute } = $query)
+</script>
+
+{#if !loading && post}
+  <!-- Use encodeDataAttribute for overlays -->
+  <h1 data-sanity={encodeDataAttribute('title')}>
+    {post.title}
+  </h1>
+{/if}
+```
+
+### Enable Visual Editing (`+layout.svelte`)
+Enable Visual Editing and Live Mode in your root layout.
+

+title: Sanity TypeGen Rules
+description: Workflow for generating TypeScript types from Sanity Schema and GROQ queries.
+---
+
+# Sanity TypeGen Rules
+
+## 1. The Workflow
+Sanity TypeGen generates TypeScript types from your schema and GROQ queries. Types can be generated automatically or manually.
+
+### Automatic (Recommended)
+Enable in `sanity.cli.ts` — types regenerate during `sanity dev` and `sanity build`:
+
+```typescript
+// sanity.cli.ts
+import { defineCliConfig } from 'sanity/cli'
+
+export default defineCliConfig({
+  typegen: {
+    enabled: true,
+  },
+})
+```
+
+### Manual
+Run the extract + generate cycle whenever schema or queries change:
+
+1.  **Extract:** Converts your Schema (TS/JS) into a static JSON representation.
+2.  **Generate:** Scans your codebase for GROQ queries and generates TypeScript types.
+
+```bash
+npx sanity schema extract && npx sanity typegen generate
+```
+
+### Watch Mode (for separate frontends)
+If your frontend is in a separate repo from the Studio, use watch mode:
+
+```bash
+npx sanity typegen generate --watch
+```
+
+## 2. The "Update Types" Pattern
+For manual workflows, implement a single script:
+
+**package.json:**
+```json
+"scripts": {
+  "typegen": "sanity schema extract && sanity typegen generate"
+}
+```
+
+### Git Strategy for Generated Files
+
+**Option A: Commit generated types (Recommended for most teams)**
+- Types available immediately after `git pull`
+- CI/CD doesn't need to run typegen
+- Can cause merge conflicts
+
+**Option B: Generate in CI (Recommended for larger teams)**
+Add to `.gitignore`:
+```gitignore
+# Sanity TypeGen (generated)
+sanity.types.ts
+schema.json
+```
+
+Then ensure CI runs typegen before build:
+```yaml
+# Example GitHub Actions
+- run: npm run typegen
+- run: npm run build
+```
+
+## 3. Configuration (`sanity.cli.ts`)
+
+> **Note:** `sanity-typegen.json` is deprecated. Move your configuration to `sanity.cli.ts`.
+
+```typescript
+// sanity.cli.ts
+import { defineCliConfig } from 'sanity/cli'
+
+export default defineCliConfig({
+  typegen: {
+    enabled: true, // Auto-generate during sanity dev/build
+    path: "./src/**/*.{ts,tsx,js,jsx,astro,svelte,vue}", // Glob to find queries
+    schema: "schema.json", // Schema file from extract
+    generates: "./sanity.types.ts", // Output file
+    overloadClientMethods: true, // Auto-type client.fetch() calls
+  },
+})
+```
+
+### Project Structure Examples
+
+**Single Repo / Embedded Studio (most common):**
+Use defaults — no extra config needed.
+
+**Monorepo** (Studio in `apps/studio`, Frontend in `apps/web`):
+```typescript
+export default defineCliConfig({
+  typegen: {
+    path: "../web/src/**/*.{ts,tsx,js,jsx}",
+    schema: "schema.json",
+    generates: "../web/sanity.types.ts",
+  },
+})
+```
+
+**Separate Repos:**
+Use `--watch` mode in your frontend: `sanity typegen generate --watch`
+
+## 4. Usage in Code
+
+### Automatic Type Inference (Recommended)
+With `overloadClientMethods: true` (default), `client.fetch()` automatically returns typed results when you use `defineQuery`:
+
+```typescript
+import { defineQuery } from "groq";
+import { createClient } from "@sanity/client";
+
+const client = createClient({...});
+
+const POSTS_QUERY = defineQuery(`*[_type == "post"]{ title, slug }`);
+
+// Return type is automatically inferred — no manual type import needed!
+const posts = await client.fetch(POSTS_QUERY);
+```
+
+### Manual Type Import (Alternative)
+You can also import generated types directly:
+
+```typescript
+import { defineQuery } from "groq";
+// Next.js re-exports defineQuery for convenience:
+// import { defineQuery } from "next-sanity";
+
+const AUTHOR_QUERY = defineQuery(`*[_type == "author" && slug.current == $slug][0]{ name, bio }`);
+
+import type { AUTHOR_QUERYResult } from "@/sanity.types";
+
+export default function Author({ data }: { data: AUTHOR_QUERYResult }) {
+  return <h1>{data.name}</h1>
+}
+```
+
+### Required Fields
+Use `--enforce-required-fields` during extraction to translate `validation: rule => rule.required()` into non-optional types:
+
+```bash
+npx sanity schema extract --enforce-required-fields
+npx sanity typegen generate
+```
+
+> **Warning:** If you use draft previews, fields may still be `undefined` even with required validation, since drafts can be in an invalid state.
+
+### Type Utilities
+TypeGen provides utilities for working with complex types:
+
+```typescript
+import type { Get, FilterByType } from 'sanity'
+import type { Page, PageBuilder } from './sanity.types'
+
+// Extract deeply nested type (up to 20 levels)
+type HeroSection = Get<Page, 'sections', number, 'hero'>
+
+// Filter specific types from unions using _type discriminator
+type HeroBlock = FilterByType<PageBuilder, 'hero'>
+```
+
+### Unique Query Names
+All queries must have unique variable names. Duplicate names across files will cause TypeGen to silently overwrite types. Use descriptive, scoped names:
+
+```typescript
+// Unique names
+const POSTS_INDEX_QUERY = defineQuery(`*[_type == "post"]{ title }`)
+const POST_DETAIL_QUERY = defineQuery(`*[_type == "post" && slug.current == $slug][0]`)
+
+// Duplicate names will conflict
+const QUERY = defineQuery(`*[_type == "post"]`)  // file-a.ts
+const QUERY = defineQuery(`*[_type == "author"]`) // file-b.ts — overwrites!
+```
+
+### Supported Query Formats
+Queries must be assigned to a variable using `groq` or `defineQuery`:
+
+```typescript
+// Works — groq template tag
+const query = groq`*[_type == "post"]`
+
+// Works — defineQuery
+const query = defineQuery(`*[_type == "post"]`)
+
+// Won't work — inline query
+await client.fetch(groq`*[_type == "post"]`)
+```
+
+### Supported File Types
+TypeGen parses queries from: `.ts`, `.tsx`, `.js`, `.jsx`, `.astro`, `.svelte`, `.vue`
+
+### tsconfig Requirements
+Ensure `sanity.types.ts` is included in your `tsconfig.json`'s `include` array. If your config restricts includes (e.g., `["src/**/*"]`) and the types file is at the project root, TypeScript won't pick up the generated types:
+
+```json
+{
+  "include": ["src/**/*", "sanity.types.ts"]
+}
+```
+
+### Skipping Individual Queries
+Add `@sanity-typegen-ignore` in a comment before a query to skip type generation:
+
+```typescript
+// @sanity-typegen-ignore
+const debugQuery = groq`*[_type == "debug"]`
+```

+title: "Sanity Visual Editing Rules"
+description: Comprehensive guide for Sanity Visual Editing, including Presentation Tool, Stega (Content Source Maps), and Overlays.
+---
+
+# Sanity Visual Editing Rules
+
+## 1. Concepts
+
+### Presentation Tool
+The Studio plugin (`sanity/presentation`) that renders your front-end application inside an iframe in the Studio. It enables the "Edit" overlay and bidirectional navigation.
+
+### Content Source Maps (Stega)
+Invisible characters embedded in strings that tell the Presentation Tool which field in which document the content comes from.
+- **Mechanism:** Sanity encodes document ID, field path, and dataset info into string values.
+- **Result:** Click-to-edit functionality in the preview.
+
+### Loaders
+Framework-agnostic or specific libraries that handle:
+1.  Fetching data (production vs. preview).
+2.  Subscribing to real-time updates (Live Content API).
+3.  Encoding Stega strings (if not handled by the Content Lake automatically).
+
+## 2. The Golden Rule of Stega (Clean Data)
+
+When Visual Editing is enabled, string fields will contain invisible characters. You **MUST** clean them before using the value for logic.
+
+| Scenario | Clean? | Why |
+|----------|--------|-----|
+| Comparing strings (`if (x === 'y')`) | ✅ Yes | Stega breaks equality |
+| Using as object keys | ✅ Yes | Keys won't match |
+| Using as HTML IDs | ✅ Yes | Invalid characters |
+| Passing to third-party libraries | ✅ Yes | May validate input |
+| Rendering text (`<h1>{title}</h1>`) | ❌ No | Breaks click-to-edit |
+| Passing to `<PortableText />` | ❌ No | Handles internally |
+| Passing to image helpers | ❌ No | Handles internally |
+
+```typescript
+import { stegaClean } from "@sanity/client/stega";
+
+export function Layout({ align }: { align: string }) {
+  // Good: Clean before comparison
+  const cleanAlign = stegaClean(align);
+  return <div className={cleanAlign === 'center' ? 'mx-auto' : ''} />
+}
+```
+
+## 3. Token Handling (Security)
+
+Store your read token in a dedicated file that throws if missing:
+
+```typescript
+// src/sanity/lib/token.ts
+export const token = process.env.SANITY_API_READ_TOKEN
+
+if (!token) {
+  throw new Error('Missing SANITY_API_READ_TOKEN')
+}
+```
+
+**Never** expose tokens in client bundles. Pass to `defineLive` for server/browser use only when Draft Mode is enabled.
+
+## 4. Setup: Presentation Tool
+
+**File:** `sanity.config.ts`
+
+```typescript
+import { defineConfig } from 'sanity'
+import { presentationTool } from 'sanity/presentation'
+import { resolve } from '@/sanity/presentation/resolve'
+
+export default defineConfig({
+  // ...
+  plugins: [
+    presentationTool({
+      resolve, // Document locations (see below)
+      previewUrl: {
+        previewMode: {
+          enable: '/api/draft-mode/enable',
+        },
+      },
+    }),
+  ],
+})
+```
+
+### Document Locations
+
+Show where documents appear in the front-end — enables quick navigation between Structure and Presentation tools.
+
+```typescript
+// src/sanity/presentation/resolve.ts
+import { defineLocations, PresentationPluginOptions } from 'sanity/presentation'
+
+export const resolve: PresentationPluginOptions['resolve'] = {
+  locations: {
+    post: defineLocations({
+      select: { title: 'title', slug: 'slug.current' },
+      resolve: (doc) => ({
+        locations: [
+          { title: doc?.title || 'Untitled', href: `/posts/${doc?.slug}` },
+          { title: 'Posts index', href: `/posts` },
+        ],
+      }),
+    }),
+    // Add more document types as needed
+  },
+}
+```
+
+## 5. Visual Editing Overlays
+
+Render `<VisualEditing />` in Draft Mode for click-to-edit overlays.
+
+**Next.js (App Router):**
+```typescript
+// layout.tsx
+import { VisualEditing } from 'next-sanity/visual-editing'
+import { draftMode } from 'next/headers'
+import { DisableDraftMode } from '@/components/disable-draft-mode'
+
+export default async function RootLayout({ children }) {
+  return (
+    <html>
+      <body>
+        {children}
+        {(await draftMode()).isEnabled && (
+          <>
+            <DisableDraftMode />
+            <VisualEditing />
+          </>
+        )}
+      </body>
+    </html>
+  )
+}
+```
+
+### Disable Draft Mode Button
+
+Useful for content authors to exit preview and see published content:
+
+```typescript
+// src/components/disable-draft-mode.tsx
+'use client'
+import { useDraftModeEnvironment } from 'next-sanity/hooks'
+
+export function DisableDraftMode() {
+  const environment = useDraftModeEnvironment()
+  // Only show outside of Presentation Tool
+  if (environment !== 'live' && environment !== 'unknown') return null
+
+  return (
+    <a href="/api/draft-mode/disable" className="fixed bottom-4 right-4 bg-gray-50 px-4 py-2">
+      Disable Draft Mode
+    </a>
+  )
+}
+```
+
+**Remix/Svelte:** See framework-specific rules for `useLiveMode` and `enableVisualEditing` patterns.
+
+## 6. SEO & Metadata (Critical)
+
+**NEVER** allow Stega strings in `<head>` tags (Title, Description, Canonical URLs). It destroys SEO rankings and looks broken in search results.
+
+-   **Next.js:** Set `stega: false` in `generateMetadata`.
+-   **General:** Explicitly clean fields used in `<title>` or `<meta>`.
+
+```typescript
+// Next.js Example — disable stega at fetch level
+export async function generateMetadata({ params }) {
+  const { data } = await sanityFetch({
+    query: SEO_QUERY,
+    stega: false // Critical
+  })
+  return { title: data.title }
+}
+```
+
+**Alternative:** If you can't disable stega at the fetch level, clean explicitly:
+
+```typescript
+import { stegaClean } from "@sanity/client/stega";
+
+export async function generateMetadata({ params }) {
+  const { data } = await sanityFetch({ query: PAGE_QUERY })
+  return { 
+    title: stegaClean(data.title),
+    description: stegaClean(data.description),
+    openGraph: { url: stegaClean(data.canonicalUrl) }
+  }
+}
+```
+
+## 7. Drag-and-Drop Reordering (Advanced)
+
+For arrays (e.g., "Related Posts"), enable drag-and-drop in the preview using `data-sanity` attributes and `useOptimistic`:
+
+```typescript
+import { createDataAttribute } from 'next-sanity'
+import { useOptimistic } from 'next-sanity/hooks'
+
+// Add data-sanity to array container
+<ul data-sanity={createDataAttribute({ id: documentId, type: 'post', path: 'relatedPosts' }).toString()}>
+  {items.map((item) => (
+    <li key={item._key} data-sanity={createDataAttribute({
+      id: documentId, type: 'post', path: `relatedPosts[_key=="${item._key}"]`
+    }).toString()}>
+      {item.title}
+    </li>
+  ))}
+</ul>
+```
+
+**Key requirements:**
+- Query must include `_key` for array items
+- Use `useOptimistic` hook for instant UI updates during mutations
+
+## 8. Optimistic Updates for Faster Editing
+
+By default, editing a field in the Presentation Tool triggers a full page re-render. For pages with many components, this can feel sluggish. **Presentation queries** solve this by fetching only the specific block being edited.
+
+### The Concept
+
+Instead of:
+1. User edits a field -> Full page query re-runs -> All components re-render
+
+You get:
+1. User edits a field -> Block-specific query runs -> Only that component re-renders
+
+### How It Works
+
+1. **Create a targeted query** that fetches just the block data using `_key`:
+
+```groq
+*[_id == $documentId][0]{
+  "heroBlock": pageBuilder[_key == $blockKey && _type == "hero"][0]{
+    title, subtitle, image
+  }
+}
+```
+
+2. **Use a presentation query hook** in your component (e.g., `usePresentationQuery` in Next.js)
+
+3. **Fall back to initial props** when not in presentation mode
+
+This pattern works for both Page Builder blocks (`pageBuilder[]`) and Portable Text blocks (`body[]`).
+
+**See framework-specific rules for implementation:**
+- Next.js: `nextjs.md` (Section 9)
+- Page Builder: `page-builder.md` (Section 5)
+- Portable Text: `portable-text.md` (Section 7)
+
+## 9. Framework Specifics
+
+| Framework | Loader Package | Key Components |
+| :--- | :--- | :--- |
+| **Next.js** | `next-sanity` | `<VisualEditing />`, `defineLive`, `usePresentationQuery` |
+| **Remix** | `@sanity/react-loader` | `createQueryStore`, `useLiveMode`, `enableVisualEditing` |
+| **Svelte** | `@sanity/svelte-loader` | `createRequestHandler`, `useLiveMode`, `enableVisualEditing` |
+| **Nuxt** | `@nuxtjs/sanity` | Automatic via module config (`visualEditing: {}`) |
+| **Astro** | `@sanity/astro` | `sanity({ useCdn: false, stega: true })` |
