+Image renderer: generate SVG and PNG from JSON specs.
+
+### New: `@json-render/image` Package
+
+Server-side image renderer powered by Satori. Turns the same `{ root, elements }` spec format into SVG or PNG output for OG images, social cards, and banners.
+
+- `renderToSvg(spec, options)` — render spec to SVG string
+- `renderToPng(spec, options)` — render spec to PNG buffer (requires `@resvg/resvg-js`)
+- 9 standard components: Frame, Box, Row, Column, Heading, Text, Image, Divider, Spacer
+- `standardComponentDefinitions` catalog for AI prompt generation
+- Server-safe import path: `@json-render/image/server`
+- Sub-path exports: `/render`, `/catalog`, `/server`

+## 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)
