## Summary
- `contentlayer2@0.4.6` is unmaintained and drags in a heavy, stale
dependency graph (esbuild pinned to 0.17–0.20, mdx-bundler, old
`@opentelemetry/core`) that was the recurring source of vuln bumps.
- Migrates all three apps that used it — `design-system`, `ui-library`,
`learn` — to [Velite](https://velite.js.org), preserving the generated
typed `allDocs`/`Doc` collection and the `body.code` + `useMDXComponent`
runtime via a small shared local hook.
- Same MDX pipeline (remark-gfm, remark-code-import, rehype-slug,
rehype-pretty-code w/ Shiki compat + local theme,
rehype-autolink-headings, custom
`__rawString__`/`__src__`/`__event__`/`__style__` visitors) ported 1:1
into each app's `velite.config.js`.
- `learn`'s extra frontmatter fields (`chapterNumber`, `explore`,
`courseHero`) are now backed by real Velite/Zod schema types, so the
`(doc as any)` casts in `get-next-page.ts` / `get-current-chapter.ts` /
the doc page could be dropped.
- `next.config.mjs` no longer wraps with `withContentlayer`; since
Velite has no Next.js webpack-plugin equivalent, each app's `dev` script
now runs `velite dev` and `next dev` in parallel via `npm-run-all`.

## Test plan
- [x] `pnpm build:content` (Velite build) succeeds for all three apps
- [x] `pnpm typecheck` passes for all three apps
- [ ] Manual smoke test of `pnpm dev` for each app in a browser (docs
pages render, TOC, copy-button, code highlighting)

## Summary by CodeRabbit
* **Improvements**
* Improved content generation across documentation, learning materials,
and the UI library for more consistent pages.
* Preserved MDX rendering, navigation, table of contents, course
metadata, source previews, and component examples.
* Improved consistency when displaying documentation and interactive
examples.
* Improved application loading by optimizing how interface components
are delivered.
* **Chores**
* Streamlined content compilation and development workflows across the
design system, learning area, and UI library.

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Feature: agent-readable markdown pages for the UI library docs.
## What is the current behavior?
Library docs are HTML-only. `llms.txt` lists page titles, but there is
no `.md` body an agent can fetch.
## What is the new behavior?
Each docs page is also served as markdown:
- Build-time MDX → markdown (`pnpm --filter library build:markdown`)
- `GET /library/docs/{slug}.md` (and `Accept: text/markdown`)
- HTML pages advertise `rel=alternate` `text/markdown`
- `llms.txt` links to the `.md` URLs
This is the base of a stack. The prompt-tab PR sits on top:
https://github.com/supabase/supabase/pull/49566
## Additional context
Interactive previews are omitted from the markdown. `BlockItem` emits
the production `npx shadcn add` command so agents still get an install
path.
## To test
1. `pnpm --filter library dev` (generates markdown in `predev`).
2. Open http://localhost:3004/library/docs/nextjs/password-based-auth.md
— markdown with the install command, file tree, and setup steps; no
interactive previews.
3. Open the same path without `.md` — HTML docs unchanged (no prompt tab
in this PR).
4. `curl -H 'Accept: text/markdown'
http://localhost:3004/library/docs/nextjs/password-based-auth` should
also return markdown.
5. http://localhost:3004/library/llms.txt — links should end in `.md`.

## Summary by CodeRabbit
* **New Features**
* Documentation pages are available as Markdown through `.md` URLs and a
dedicated endpoint.
* Markdown is generated automatically during development and production
builds.
* Generated content preserves front matter, links, callouts,
installation instructions, and supported documentation elements.
* Installation commands support npm, pnpm, yarn, and bun for React and
Vue projects.
* **Bug Fixes**
* Improved Markdown file handling, link rewriting, and content
negotiation.
* **Tests**
* Added coverage for Markdown conversion, content negotiation, and
installation commands.

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
- Noticing our code we have many patterns of calling localstorage and
handling those errors
- We should add those in a single well tested file
- Handle those errors in the singleton which makes it easier for us to
debug customer issues. Logger is outputing local storage warnings for
feature we expose
- Side effect of this is random crashes on studio when local storage
isn't available or handled correctly

## Summary by CodeRabbit
* **Refactor**
* Improved browser storage handling across the app for more reliable
persistence and graceful behavior in restricted or non-browser
environments (settings, previews, charts, tabs, sign-in/session flows,
integrations, and UI state).
* **New Features**
* Introduced a safe storage layer to standardize and harden
local/session persistence.
* **Tests**
* Added comprehensive tests covering the new safe storage behavior.
