Launch

cd apps/docs && pnpm dev   # Next.js + Turbopack, ready in <1s on :3000

Wait for Ready in in the log. Port 3000; kill with lsof -ti:3000 | xargs kill.

Drive

Playwright is installed globally (asdf node), not in the repo. From a scratch dir, symlink the global modules so import { chromium } from "playwright" resolves:

ln -sfn "$(npm root -g)" <scratchdir>/node_modules

Use a 1280x960 viewport — the mobile demos render a centered phone frame on desktop widths. Key surfaces:

• Mobile demos: /demo/<app> (e.g. /demo/google-photos). Transitions are the product — capture mid-transition frames with waitForURL + ~120ms delay, and let animations settle ~1200ms before asserting final state.
• Remount checks: tag a DOM node (el.__tag = "x") before navigating, re-read after — survives ⇔ no remount (used for the bottom-nav/nested-boundary shell).
• Docs pages: /docs/...; llms files are static from public/ (/llms.txt, /llms/*.txt).

Gotchas

• google-photos "Collage" entry is a <button> with router.push, not a link.
• Dev console shows a pre-existing CORS error for unpkg.com/react-grab — noise.
• Stale .next/types validator errors after moving route files — ignore; regenerated on next dev/build.
