- GET /api/video/library -> {movies, shows} from video.db (VideoDatabase.
list_movies/list_shows; shows carry episode_count + owned_count).
- Library page (video-library subpage, isolated video-library.js): tabbed
Movies/Shows grid of poster cards, count, empty-state. A 'Scan Library'
button POSTs /api/video/scan/request then polls /api/video/scan/status,
showing live phase/counts, and refreshes the grid when done.
- Reuses the music dashboard-header chrome (icon title, sweep hidden) + the
watchlist-button styling for the scan button; video-card grid styles added.
- All data-attr wired (no inline onclick); module is an isolated IIFE that
listens for soulsync:video-page-shown. 105 tests green.
Now: video.db -> scanner -> /api/video -> live dashboard + Library page, all
isolated from music. Scanner adapters await live Plex/Jellyfin validation.
