+## Releases
+
+This monorepo uses [Changesets](https://github.com/changesets/changesets) for versioning and publishing.
+
+### Fixed version group
+
+All public `@json-render/*` packages are in a **fixed** group (see `.changeset/config.json`). A changeset that bumps any one of them bumps all of them to the same version. You only need to list the packages that actually changed in the changeset front matter — the fixed group handles the rest.
+
+### Preparing a release
+
+When asked to prepare a release (e.g. "prepare v0.12.0"):
+
+1. **Create a changeset file** at `.changeset/v0-<N>-release.md` following the existing pattern:
+   - YAML front matter listing changed packages with bump type (`minor` for feature releases, `patch` for bug-fix-only releases)
+   - A one-line summary, then `### New:` / `### Improved:` / `### Fixed:` sections describing each change
+   - Always list `@json-render/core` plus any packages with actual code changes
+2. **Do NOT bump versions** in `package.json` files — CI runs `pnpm ci:version` (which calls `changeset version`) to do that automatically
+3. **Do NOT manually write `CHANGELOG.md`** entries — `changeset version` generates them from the changeset file
+4. **Add new packages to the fixed group** in `.changeset/config.json` if they should be versioned together with the rest
+5. **Fill documentation gaps** — every public package should have:
+   - A row in the root `README.md` packages table
+   - A renderer section in the root `README.md` (if it's a renderer)
+   - An API reference page at `apps/web/app/(main)/docs/api/<name>/page.mdx`
+   - An entry in `apps/web/lib/page-titles.ts` and `apps/web/lib/docs-navigation.ts`
+   - An entry in the docs-chat system prompt (`apps/web/app/api/docs-chat/route.ts`)
+   - A skill at `skills/json-render-<name>/SKILL.md`
+   - A `packages/<name>/README.md`
+6. **Run `pnpm type-check`** after all changes to verify nothing is broken
+
+### CI scripts
+
+- `pnpm changeset` — interactively create a new changeset
+- `pnpm ci:version` — run `changeset version` + lockfile update (CI only)
+- `pnpm ci:publish` — build all packages and publish to npm (CI only)

+
+All renderers share the same workflow:
+
+1. Define a catalog with `defineCatalog`
+2. AI generates a JSON spec
+3. The renderer turns the spec into platform-native output

+
+## React
+
+Render specs as React component trees in the browser. Supports data binding, streaming, actions, validation, visibility, and computed values.
+
+```tsx
+import { defineRegistry, Renderer } from "@json-render/react";
+import { schema } from "@json-render/react/schema";
+
+const { registry } = defineRegistry(catalog, { components });
+<Renderer spec={spec} registry={registry} />
+```
+
+Use `StateProvider`, `VisibilityProvider`, and `ActionProvider` for full interactivity. See the [@json-render/react API reference](/docs/api/react) for details.
+
+## Vue
+
+Vue 3 renderer with full feature parity with React: data binding, visibility, actions, validation, repeat scopes, and streaming.
+
+```typescript
+import { defineRegistry, Renderer } from "@json-render/vue";
+import { schema } from "@json-render/vue/schema";
+
+const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: ({ props, children }) =>
+      h("div", { class: "card" }, [h("h3", null, props.title), children]),
+  },
+});
+```
+
+Uses composables (`useStateStore`, `useStateBinding`, `useActions`, etc.) instead of React hooks. See the [@json-render/vue API reference](/docs/api/vue) for details.
+
+## shadcn/ui
+
+36 pre-built components using Radix UI and Tailwind CSS. Built on top of `@json-render/react` -- no custom renderer needed.
+
+```tsx
+import { defineCatalog } from "@json-render/core";
+import { schema } from "@json-render/react/schema";
+import { defineRegistry, Renderer } from "@json-render/react";
+import { shadcnComponentDefinitions } from "@json-render/shadcn/catalog";
+import { shadcnComponents } from "@json-render/shadcn";
+
+const catalog = defineCatalog(schema, {
+  components: {
+    Card: shadcnComponentDefinitions.Card,
+    Button: shadcnComponentDefinitions.Button,
+  },
+});
+
+const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: shadcnComponents.Card,
+    Button: shadcnComponents.Button,
+  },
+});
+```
+
+See the [@json-render/shadcn API reference](/docs/api/shadcn) for the full component list.
+
+## React Native
+
+Render specs as native mobile views. Includes 25+ standard components and standard action definitions.
+
+```tsx
+import { defineCatalog } from "@json-render/core";
+import { schema } from "@json-render/react-native/schema";
+import { standardComponentDefinitions, standardActionDefinitions } from "@json-render/react-native/catalog";
+import { defineRegistry, Renderer } from "@json-render/react-native";
+
+const catalog = defineCatalog(schema, {
+  components: { ...standardComponentDefinitions },
+  actions: standardActionDefinitions,
+});
+
+const { registry } = defineRegistry(catalog, { components: {} });
+<Renderer spec={spec} registry={registry} />
+```
+
+See the [@json-render/react-native API reference](/docs/api/react-native) for details.
+
+## Image
+
+Generate SVG and PNG images from JSON specs using Satori. Ideal for OG images, social cards, and banners.
+
+```typescript
+import { renderToSvg, renderToPng } from "@json-render/image/render";
+
+const svg = await renderToSvg(spec, { fonts });
+const png = await renderToPng(spec, { fonts });
+```
+
+Nine standard components: Frame, Box, Row, Column, Heading, Text, Image, Divider, Spacer. PNG output requires `@resvg/resvg-js` as an optional peer dependency.
+
+See the [@json-render/image API reference](/docs/api/image) for details.
+
+## React PDF
+
+Generate PDF documents from JSON specs using `@react-pdf/renderer`. Render to buffer, stream, or file.
+
+```typescript
+import { renderToBuffer, renderToStream, renderToFile } from "@json-render/react-pdf";
+
+const buffer = await renderToBuffer(spec);
+const stream = await renderToStream(spec);
+await renderToFile(spec, "./output.pdf");
+```
+
+Standard components include Document, Page, View, Row, Column, Heading, Text, Image, Table, List, Divider, Spacer, Link, and PageNumber.
+
+See the [@json-render/react-pdf API reference](/docs/api/react-pdf) for details.
+
+## Remotion
+
+Turn JSON timeline specs into video compositions with Remotion.
+
+```tsx
+import { Player } from "@remotion/player";
+import { Renderer } from "@json-render/remotion";
+
+<Player
+  component={Renderer}
+  inputProps={{ spec }}
+  durationInFrames={spec.composition.durationInFrames}
+  fps={spec.composition.fps}
+  compositionWidth={spec.composition.width}
+  compositionHeight={spec.composition.height}
+/>
+```
+
+Uses a timeline spec format with compositions, tracks, and clips. Includes standard components (TitleCard, TypingText, ImageSlide, etc.), transitions (fade, slide, zoom, wipe), and effects.
+
+See the [@json-render/remotion API reference](/docs/api/remotion) for details.
+
+## Custom Renderers
+
+You can build your own renderer for any output target. See the [Custom Schema & Renderer](/docs/custom-schema) guide for how to define a custom schema and wire it to your own rendering logic.

+# @json-render/image
+
+Image renderer for `@json-render/core`. Generate SVG and PNG images from JSON specs using [Satori](https://github.com/vercel/satori).
+
+## Install
+
+```bash
+npm install @json-render/core @json-render/image
+```
+
+For PNG output, also install the optional peer dependency:
+
+```bash
+npm install @resvg/resvg-js
+```
+
+## Quick Start
+
+### Render a spec to SVG
+
+```typescript
+import { renderToSvg } from "@json-render/image/render";
+import type { Spec } from "@json-render/core";
+
+const spec: Spec = {
+  root: "frame",
+  elements: {
+    frame: {
+      type: "Frame",
+      props: { width: 1200, height: 630, backgroundColor: "#1a1a2e" },
+      children: ["heading", "subtitle"],
+    },
+    heading: {
+      type: "Heading",
+      props: { text: "Hello World", level: "h1", color: "#ffffff" },
+      children: [],
+    },
+    subtitle: {
+      type: "Text",
+      props: { text: "Generated from JSON", fontSize: 24, color: "#a0a0b0" },
+      children: [],
+    },
+  },
+};
+
+const svg = await renderToSvg(spec, {
+  fonts: [
+    {
+      name: "Inter",
+      data: await fetch("https://example.com/Inter-Regular.ttf").then((r) =>
+        r.arrayBuffer()
+      ),
+      weight: 400,
+      style: "normal",
+    },
+  ],
+});
+```
+
+### Render to PNG
+
+```typescript
+import { renderToPng } from "@json-render/image/render";
+
+const png = await renderToPng(spec, {
+  fonts: [
+    {
+      name: "Inter",
+      data: await readFile("./Inter-Regular.ttf"),
+      weight: 400,
+      style: "normal",
+    },
+  ],
+});
+
+// Write to file
+await writeFile("output.png", png);
+```
+
+### With a custom catalog
+
+```typescript
+import { defineCatalog } from "@json-render/core";
+import { schema, renderToSvg } from "@json-render/image";
+import { standardComponentDefinitions } from "@json-render/image/catalog";
+import { z } from "zod";
+
+const catalog = defineCatalog(schema, {
+  components: {
+    ...standardComponentDefinitions,
+    Badge: {
+      props: z.object({
+        label: z.string(),
+        color: z.string().nullable(),
+      }),
+      slots: [],
+      description: "A colored badge label",
+    },
+  },
+});
+```
+
