Season selection is now switchable via a view toggle (persisted): poster RAIL
(scrollable season cards w/ coverage), TIMELINE band (segments sized by episode
count, filled by owned), TABS (pills), and the LIST dropdown. All drive the same
selection; episodes fade in on change.
- Watchlist button is now REAL: toggles shows.monitored via POST /api/video/monitor
(set_monitored), reflects 'In Watchlist' state. show_detail returns monitored.
- 'Get Missing' + a 'Missing only' toolbar toggle filter the episode list to
unowned episodes (actual downloading is the future acquisition subsystem).
Seam tests for the monitor endpoint + bad-input guards; shell hooks updated.
Backend for the upcoming TV/movie detail pages, isolated to video.db:
- show_detail(id): show + seasons->episodes tree with owned/total roll-ups
(season 0 -> 'Specials', missing-season-row episodes still grouped).
- movie_detail(id): movie + owned flag + best media-file (resolution/quality).
- get_art_ref generalizes the poster ref to poster|backdrop; new
/api/video/backdrop/<kind>/<id> streams the hero art server-side (Jellyfin
Backdrop vs Primary handled).
- /api/video/detail/{show,movie}/<id> endpoints.
Seam tests for the tree roll-ups, owned/file, art ref, and both endpoints.
