- barrel re-exports domains with `export type *` (not `export *`) so the
internal downloadsApi/plexApi/messagingApi slices stay behind the façade;
plex's runtime value exports (EMPTY_PLEX_FILTERS/plexFilterCount) re-exported
explicitly
- App.tsx: drop the now-redundant `prefs as Record<string, unknown>` self-cast
(Me.preferences is already that type) and its `prefsRec` alias
- plex.ts: comment why plexSetState keeps its status union inline (reusing
VideoStatus would make an api.ts↔plex.ts type cycle)
Behaviour-identical. Gate green: typecheck, eslint 0, prettier, 74 vitest.
All Plex types (browse cards, show/season/item details, collections, native
playlists, filters/facets, watch-link) + EMPTY_PLEX_FILTERS/plexFilterCount/
appendPlexFilters + the ~40 plex methods move into a self-contained api/plex.ts
exporting a `plexApi` slice (imports only core's req/beacon). api.ts spreads the
slice and re-exports the types via `export *`. api.ts 1352 -> 882 lines (halved
from the original 1793); no runtime change. Gate green: typecheck, eslint,
prettier, 74 vitest.
