An infinite radio appends forever: cap the queue at QUEUE_CAP, trimming only
already-played entries (keep KEEP_BEHIND for prev-nav), and send only the most
recent EXCLUDE_WINDOW ids as "don't repeat" so the request and server NOT IN
don't grow unbounded.

"Start radio" in the track menu seeds the queue from a track; RadioController
(headless, in AppShell) tops it up via /radio/next as it drains. QueuePanel's
radio scaffolding is now live: the exploration slider drives familiar<->new and
each entry shows its reason ("why this is playing"). Adds the radio endpoints
(start/next/similar), radio context + actions on the queue slice, and the pick->
entry mapper. Degrades to metadata picks while ML is offline.

Full-screen overlay expanded from the persistent player: big artwork or a
Lyrics tab. Synced (LRC) lyrics highlight the active line by playback position,
auto-scroll, and seek on tap; plain text is the fallback; missing lyrics offers
a re-fetch. Adds lyrics endpoint + LRC parser + isNowPlayingOpen player state.

The Tier-2 rehydrated cache seeded fulfilled entries at startup, so RTKQ served stale data and never hit the network (manual metadata edits, etc. only appeared after clearing the cache). Enable refetchOnMountOrArgChange + refetchOnReconnect + refetchOnFocus and wire setupListeners, so the cached snapshot still shows instantly but the server silently revalidates it whenever reachable.

The Library showed a blocking error with the backend unreachable. Now it
composes a read-only library from everything already in the RTK Query
cache (Tier-2 rehydrated last-seen data + anything fetched this session),
so it keeps rendering offline instead of erroring.
- selectors: `selectLocalTracks/Albums/Artists` — memoized, union + dedupe
across getTracks/getAlbums/getArtists, the per-album/artist list
endpoints, and single-entity fetches; skips pending/rejected entries
- LibraryPage: when offline, fall back to the composed lists (live data
still wins online), filter client-side for search, show an offline
banner, and never show the retry-only ErrorState
- i18n: `library.offline.*` (en + ru)
- test: selector composition / dedup / status filtering (3 cases)

Replace the labelled availability/metadata badges in track rows with
small icon+tooltip indicators (cloud/hard-drives/warning/etc, derived
from TrackAvailability and MetadataStatus).
Add a `connection` slice fed by a single status poller (Sidebar) so
other components can cheaply check backend reachability. TrackRow uses
this plus the offline audio cache to show "Local" instead of a stale
"On server" when the backend is down but the track is already cached.
Add a play overlay button shown on cover art hover that inserts the
track into the queue right after the current track and jumps to it,
so it takes priority over what's already queued. Replaces the
double-click-to-play interaction with a new playNow queue action.
Add a right-side track info drawer that sits to the right of the queue
panel when both are open. Shows a large cover, title/artist/album links,
a Play/Queue/Edit actions row, and Status/General/File/Identifiers
sections (empty rows omitted). Opens from the track context menu, the
player now-playing tile, and the queue now-playing card.
- ui slice: trackInfoId + open/closeTrackInfo
- TrackInfoDrawer rendered after QueuePanel in AppShell; overlays content
on narrow viewports
- map source/createdAt/enrichedAt from the wire (were unmapped)
- formatDateTime helper, info icon, i18n (en/ru)
- drop orphaned toggleNowPlaying/isNowPlayingOpen from player slice

RTK Query 2.12's invalidation slice reads `provided.tags` during cache
rehydration (`Object.entries(provided.tags ?? {})`). Our persisted
snapshot only carried `{ queries, mutations }`, so `provided` was
undefined and `.tags` threw on every startup with a cached snapshot —
crashing the app inside the rehydrate reducer / immer produce.
Snapshot now carries the real `provided` (so invalidation tags
rehydrate), and `load()` defaults it to `{ tags: {}, keys: {} }` so
snapshots persisted before this field existed recover without a manual
localStorage clear.

Replace the faked ConnectPage login with a real /auth/login -> /auth/me
flow, including loading/error states. Add a backend-contract adapter layer
(api/mappers.ts) translating the backend's snake_case, lean *Out schemas and
{items,total,limit,offset} paging into the UI's camelCase domain types, so
swapping backends only touches the mappers.
- auth: chained login (tokens) + /auth/me (user); refresh on snake_case;
expiresIn optional (reauth is 401-driven, backend sends no TTL)
- streaming: GET /stream/{id}?token= (token query param for <audio>); SW
audio cache route + tests follow the path change (token stays cache-stable)
- library/playlists/likes/admin: correct paths (/tracks not /library/tracks),
page/pageSize<->limit/offset, duration_seconds->durationMs, likes as
append-only POST /likes event-log, admin is_superuser<->role
- downloads/storage: marked provisional (backend routes still stubs)

Three tiers of offline support, all scoped to the active backend's
localStorage namespace (mirroring the auth slice):
Tier 1 — persist client state. queue + player slices are saved (queue
entries/index/source; player track/position/volume/repeat/shuffle) and
rehydrated on load, so a reload with no backend restores where the user
left off. Playback never auto-resumes (browsers block autoplay). Retires
the DEMO_QUEUE and isQueueOpen:true stubs.
Tier 2 — persist the RTK Query cache. Last-seen library/albums/artists
are snapshotted (fulfilled queries only) and replayed via RTKQ's
extractRehydrationInfo at startup, so the library renders read-only when
the backend is down. ConnectionStatus tooltip flags cached data offline.
No server data is copied into a slice — the cache feeds itself back.
Tier 3 — service worker audio + cover cache (PWA). Audio streams are
cached keyed by content id (token stripped), range-aware (synthetic 206
slicing), with a 500MB LRU cap, so already-played tracks play fully
offline. Cover art uses stale-while-revalidate in its own bounded cache.
Module worker (ESM); pure helpers split into sw-core.js and unit-tested.
Web app manifest enables "Install app". Player source badge now reflects
real cached state.
tsc clean, lint clean, 19 new tests pass, production build verified.
