4gray 6578e4073c feat(dashboard): portal EPG on the live rails, loaded lazily per visible card (#1638)
Xtream and Stalker live cards on the dashboard carried no XMLTV key, so the
rails never asked anything for them and showed only the LIVE chip. Their
programme now comes from the portal, one card at a time and only once the card
is on screen.

- `lib-dashboard-rail` reports the cards inside its viewport through an
  IntersectionObserver rooted at the track; `DashboardLiveEpgPresenter` unions
  them with the pinned hero row and hands the set to
  `DashboardPortalLiveEpgPresenter`.
- `DashboardPortalLiveEpgService` runs the bounded queue — two requests in
  flight, 200 ms apart, one card each — through
  `StreamResolverService.loadEpgForItems`, publishing every answer the moment
  it lands, so the page never waits and a slow portal delays no other card. A
  card scrolled past before its turn is never requested.
- A programme is trusted for 60 s, an empty answer for 30 s (the resolver
  reports a dead portal and a guide-less channel identically), and a
  completion captures both the display offset and the EPG source revision,
  requeueing itself when either moved.
- The presenter hands its wanted set back on destroy. Desktop only: the shared
  collection resolver is gated on the local XMLTV bridge.
- A shimmer placeholder shows only before a card's first portal answer; M3U
  cards keep the batched XMLTV lookup.

Workspace Dashboard Feature

This library owns the workspace dashboard rails UI. The dashboard is a read-only surface over existing playlist, recent, favorites, EPG, and Xtream catalog data; it should not introduce Electron IPC, SQLite schema, or route contracts on its own.

Dashboard Surfaces

The dashboard renders a surface only when the matching setting is enabled. Data rails also require the underlying data slice to have at least one item.

  • hero shows the large top banner for the most recent global item. When that item is a live TV channel, the hero looks up the current XMLTV programme and displays the programme title, time range, and EPG progress bar when data is available.
  • continueWatching shows recent movies and series from DashboardDataService.globalRecentVodItems() using cover cards with playback progress when a saved resume position is available.
  • liveFavorites shows favorited live TV channels from DashboardDataService.globalFavoriteLiveItems() using the channel layout with EPG title, time range, and progress when XMLTV data is available.
  • recentlyWatchedLive shows recently watched live TV channels from DashboardDataService.globalRecentLiveItems() using the same channel layout.
  • favoriteMoviesAndSeries shows favorited movies and series from DashboardDataService.globalFavoriteItems(), excluding live favorites, using cover cards.
  • recentSources shows recently used playlist/source entries.
  • xtreamRecentlyAdded shows recently added Xtream catalog items.
  • tmdbRecommendations shows "Because you watched X" — TMDB recommendations seeded from recently watched movies/series, kept to titles that exist in an imported Xtream library. Needs the TMDB opt-in and the Electron DB worker (hidden in the PWA), and hides itself below five matched cards. Data: DashboardRecommendationsService in workspace/dashboard/data-access.
  • tmdbTrending shows TMDB's weekly trending titles, matched against the imported Xtream libraries. Same TMDB/Electron gating; unmatched cards open the global search prefilled. Data: DashboardTrendingService.

Settings

Per-surface visibility lives on Settings.dashboardRails as a DashboardRailsSettings object. Every surface defaults to enabled. Stored settings are deep-merged with DEFAULT_DASHBOARD_RAILS_SETTINGS by SettingsStore, so existing users and older partial settings keep newly added surfaces visible unless they explicitly turn them off.

The global showDashboard flag remains a top-level Settings property because workspace startup and route guards already depend on that contract. The Settings UI groups showDashboard and the per-surface checkboxes in the Dashboard section. When showDashboard is off, the per-surface checkboxes are disabled because the dashboard route itself is hidden.

Navigation

Rail cards use the navigation state provided by DashboardDataService for the underlying item. Rail "See all" links may also pass router state:

  • live rails open the relevant collection on Live TV.
  • cover rails for movies/series open Global Recent or Global Favorites on Movies when movie items are present, otherwise on Series.

This keeps the global collection pages from defaulting to Live TV when a dashboard rail is clearly about movies or series.
