+Series detail pages now list the cast of the whole show instead of only its
+newest season, so actors who left partway through stop disappearing from
+long-running shows — while people who joined for the current season still
+show up.

 - Dashboard: opt-in "Trending this week" rail (weekly TMDB trending matched against imported Xtream playlists via one batched `DB_MATCH_TITLES` request; Electron-only, `dashboardRails.tmdbTrending` toggle) and hero TMDB extras (backdrop fallback, rating + genre badges, memoized per session; series heroes show the tracked S/E badge from playback positions) — `DashboardTrendingService` in `libs/workspace/dashboard/data-access`, `DashboardHeroTmdbService` in `libs/workspace/dashboard/feature`; both load async after first paint
 - Series detail views show a TMDB production-status chip (`tmdb_status`, e.g. Ended / Returning) — TMDB sends `status` in English regardless of request language, so it is normalized to a token by `normalizeSeriesStatus` and rendered via `seriesStatusLabelKey` translations; person pages show `deathday` alongside `birthday`

 - Opt-in via `Settings > Metadata (TMDB)` (sends titles to TMDB); the section also has a "check key" button and a cache panel (row count + payload size, with a clear button); optional user API key overrides the embedded default (`DEFAULT_TMDB_API_KEY` in `libs/services/src/lib/tmdb/tmdb-config.ts` — an empty placeholder in the repo by design; the real key lives in the `TMDB_API_KEY` GitHub Actions secret and is injected at CI build time by `tools/tmdb/inject-tmdb-key.mjs`)
 - Match confidence: a provider `tmdb_id` is a strong hint, not gospel — its payload is weighed against the item (`assessProviderId`: title or year agrees → use it; both years known and incompatible → the search may take over; title-only mismatch → keep it, since TMDB localizes titles). A 404 marks the id dead (`badProviderId:<id>` row); transient failures never do. Without a usable id: normalized-title + year (±1) search with a strict gate — no confident match means no enrichment
