+- Video tours are Playwright-based screen recordings (not tests) in `video-tours/`.
+- Run all tours (desktop): `yarn tour`
+- Run all tours (mobile): `yarn tour:mobile`
+- Videos are saved to `video-tours/output/` (git-ignored).
+- Tour files use `.tour.ts` suffix in `video-tours/tours/`.
+- Helpers: `injectVisibleCursor()`, `moveThenClick()`, `moveThenType()`, `smoothScroll()` in `video-tours/helpers.ts`.
+- Fixtures provide a `tourPage` with visible cursor overlay via `video-tours/tours/fixtures.ts`.
