57bb297bff Add skip intro / next episode at credits, via Emby's own detection
Some checks failed
Publier l'image Docker / test (pull_request) Failing after 4s
Publier l'image Docker / publish (pull_request) Has been skipped
Asked for directly. Checked the real server before building anything:
no plugin provides this (Cinema Intros is a different feature - pre-show
trailers, not per-episode skip points), and Emby's own Chapters field
turned out to be auto-generated placeholders every 5 minutes, not real
markers.

What the server does have natively, confirmed from its own
/openapi.json rather than assumed: a per-library EnableMarkerDetection
option backed by a built-in "Detect Episode Intros" scheduled task -
audio-fingerprint detection, the same idea as Jellyfin's separate Intro
Skipper plugin, already part of Emby itself. Enabling it (done directly
on the server for the two TV libraries) adds real entries to the same
Chapters array, distinguished by MarkerType: IntroStart/IntroEnd/
CreditsStart.

This made the feature almost entirely "read what Emby already
computed" - no fingerprinting, no new persistence, no background jobs
of this app's own. CatalogService.getPlaybackMarkers fetches
Fields=Chapters and picks out just those three marker types (nulls
when detection hasn't reached this item or isn't enabled for its
library - never an error), behind a new
GET /api/catalog/item/:id/markers route mirroring getPlaybackOptions.

The player gets one new floating button, #skipIntroBtn - an explicit
label, not an icon, matching this app's own convention for every
request-shaped control. It's a sibling of #bottomBar, not inside it,
so it stays reachable through the bar's own auto-hide/.minimal collapse.
Clicking it seeks to introEndTicks through the exact same
activeDriver/onDriverStateChanged path any other seek uses, so it's
automatically host-only and automatically cast-aware with no new
special-casing for either. End credits got no button of their own -
#nextBtn already does exactly "go to the next queued item" and was
already shown whenever hasNextQueued is true; the only gap closed here
is visibility, by un-minimizing the bar once (a one-shot flag, not a
fight against someone deliberately re-minimizing it) the moment
playback crosses creditsStartTicks.

Verified: full typecheck/test/build on both projects (125/125 server
tests, including new coverage for getPlaybackMarkers - real MarkerType
values mixed with auto-generated Chapter ones, and both "no Chapters"
and "no markers among the Chapters" resolving to nulls rather than
throwing). The button's on-screen position was checked directly
(getBoundingClientRect against the real compiled CSS) at two viewport
sizes - clear of #bottomBar with a 10px gap, not overlapping. Not
verified: the detection task had only just been enabled on the real
server and hadn't finished analyzing any episode yet, so the actual
end-to-end "a detected marker makes the button appear at the right
second" behavior needs a real check once it's had time to run.

4efcd67fb3 Sync text subtitle choice too, and fix an empty audio option
All checks were successful
Publier l'image Docker / test (push) Successful in 23s
Publier l'image Docker / publish (push) Successful in 14s
Bug report: watch party members still didn't have synced subtitle
settings, and the audio/language selector showed an empty choice on
first load.

Text subtitles were the gap left by the previous "one shared stream
per party" change: that made audio/quality/burn-in host-only and
party-wide, but a plain text subtitle pick (the common case - burn-in
only applies to bitmap PGS/VobSub/DVB tracks) was still each viewer's
own local <track> choice. Once people actually watched together,
"everyone but me changed the subtitle" read as broken sync.

Fixed with a parallel mechanism, not a merge into burnInSubtitleIndex -
new Party.textSubtitleIndex, new setTextSubtitle/textSubtitleChanged
socket pair, mirroring setBurnInSubtitle/burnInChanged's host-only,
request/broadcast/react shape exactly. Kept separate from burn-in
(rather than reusing one field for both) to avoid touching the
already-proven burn-in path - only one subtitle can show at once, so
the two are mutually exclusive, enforced server-side in both
directions: a real pick on either clears the other. Clearing one to
null/"Aucun" is deliberately not treated as a pick for this purpose,
so it doesn't clobber an unrelated choice in the other field.

Mechanically the two still work nothing alike: burn-in changes the
actual encoded stream (ffmpeg), so it reloads for everyone; a text
pick only swaps which native <track> each member already renders
locally - no reload, no transcode, unless it's the one clearing an
active burn-in, which does still need the reload since the stream
itself changes back to the normal shared one.

Player.ts's subtitle <select> gating stopped being conditional on
burn-in - it's simply host-gated now, matching audio/quality, and its
value restores from whichever kind of pick (if any) the party
currently has.

Second, unrelated bug in the same report: audioSelect.value =
streamAudioIndex || '' assigned an empty string whenever no audio
track had been picked yet (the common default) - since a real
audio-track <option> never has value="", this matched nothing and
left the select at selectedIndex=-1, a genuinely empty-looking choice.
Fixed at both call sites (loadTrackOptions, onStreamOptionsChanged) by
only assigning .value when truthy.

Server: SocketGateway tests cover setTextSubtitle's host-only gating,
broadcast, music no-op, and mutual exclusivity in both directions;
PartyService tests cover textSubtitleIndex through create/
advanceQueue/toPublicState. Full typecheck/test/build green on both
projects (91/91 server tests). Real-browser check (mocked-fetch + real
bundle) confirmed: a follower's subtitle select renders disabled
regardless of burn-in state; a host's select restores the party's
current text or burn-in pick on load; and the audio select now lands
on a real first option instead of an empty one.

Not addressed here (raised in the same report, need more diagnostic
detail first): occasional sync losses between clients, and a
suspicion that per-user watch-status (Emby PlaystateService sync)
might be broken.

f78b2f1408 One shared Emby stream per party, not one per viewer
All checks were successful
Publier l'image Docker / test (push) Successful in 21s
Publier l'image Docker / publish (push) Successful in 20s
Asked for directly: exactly one stream should ever be open between this
app and Emby per party, no matter how many members it has. Before this,
every viewer's own <video>/<audio> independently negotiated its own
PlaybackInfo and got its own PlaySessionId - a party of 5 meant Emby
transcoding the same title 5 separate times.

A bigger, higher-regression-risk change than most of this session's
other work: it replaces the core playback path every existing party
already relies on (CatalogService.proxyStream and its route are gone
entirely) rather than adding something alongside it - there's no other
consumer of the per-viewer path, and the ask was explicit that there
should only ever be one mechanism.

- server/src/services/CatalogService.ts: proxyStream's negotiate-then-
  build-a-target logic extracted into negotiateStreamTarget(session,
  itemId, isAudio, audioStreamIndex, maxStreamingBitrate) - identical
  logic, returns the target instead of proxying it directly so it can
  be cached. proxyStream/proxyRawStreamAsset removed.
- server/src/services/PartyStreamService.ts (new): one negotiated
  target per party.id, reused by every member; renegotiates when the
  desired item/audio/quality changes. Recovers from a dead upstream
  session with no new plumbing - EmbyClient.proxyResponse already sets
  res.statusCode before writing the body, so a failed proxied response
  is detected right after it resolves and the cache entry is dropped,
  so the next request (a manual retry, or the next segment fetch)
  renegotiates fresh instead of repeating the same dead target forever.
- server/src/emby/EmbyClient.ts: rewritePlaylist/proxyResponse's
  trailing itemId param genericized to routeKey - it's only ever read
  back to build the raw-asset URL, so it's party.id for the new stream
  routes and an inert real itemId for proxyImage/proxySubtitle (which
  never reach that branch anyway).
- server/src/index.ts: GET /api/catalog/party-stream/:partyId/
  master.m3u8 and .../raw replace /api/catalog/stream/:itemId/...
  entirely, membership-checked like the burn-in routes; a new idle-reap
  interval for PartyStreamService, same shape as TranscodeService's own.
- Forced consequence of "one stream", not a free design choice: audio
  track/quality become a host-only, party-wide choice for video -
  Party.streamAudioIndex/streamQuality, setStreamOptions/
  streamOptionsChanged, byte-for-byte the same shape
  setBurnInSubtitle/burnInChanged already established for burn-in
  subtitles. server/src/realtime/SocketGateway.ts gains the host-only,
  video-only handler; server/src/services/PartyService.ts resets
  streamAudioIndex (not streamQuality - a bandwidth preference isn't
  item-specific) on advanceQueue, same reasoning as burnIn* already
  gets; MusicQueueService.playNext ends the party's cached session on
  a track change.
- client/src/api/embyApi.ts: streamUrl/audioStreamUrl replaced by one
  partyStreamUrl(partyId) - no query params needed any more, the party
  itself is the source of truth for what it's streaming.
- client/src/api/party.ts: setStreamOptions/onStreamOptionsChanged.
- client/src/views/player/Player.ts: audio/quality <select>s disabled
  for a follower (applyStreamOptionsGating, mirroring
  renderSubtitleOptions' own gating), restore the party's current
  choice on load/broadcast, and a host's change calls setStreamOptions
  instead of reloading locally - every member (host included) only
  ever reacts to the resulting broadcast, same discipline the rest of
  this player already uses. Dead reloadWithCurrentOptions removed.
- client/src/musicBar/MusicBar.ts: loadTrack points at
  partyStreamUrl(activePartyId) - no picker to gate, MusicBar never had
  one.
- server/test/catalogService.test.ts: proxyStream's old cases moved to
  exercise negotiateStreamTarget instead, plus new quality-override and
  no-source-fails cases. server/test/partyStreamService.test.ts (new):
  cache hit/miss/param-change/item-change, the failure-invalidation
  path, endSession, idle reap. server/test/socketGateway.test.ts:
  setStreamOptions host-only gating + broadcast, mirroring the existing
  setBurnInSubtitle tests.
- docs/architecture.md, README.md: design, the forced audio/quality
  trade-off spelled out, and what's still unverified (a different kind
  than this session's other Emby-API guesses - the calls themselves
  were already live code, what's untested is real multi-viewer load).

Verified: full typecheck+test+build on both projects (85/85 server
tests, 12 new). A real-browser check (mocked-fetch + real bundle, this
session's standing harness) confirmed a follower's audio/quality
selects render disabled and a host's render enabled, from the same
party data with only youAreHost flipped.

26da8fc5dc Self-hosted ffmpeg pipeline for PGS (image) subtitle burn-in
All checks were successful
Publier l'image Docker / test (push) Successful in 25s
Publier l'image Docker / publish (push) Successful in 30s
Asked for directly, right after the client-side <track> redesign closed
every *text* subtitle case: PGS/VobSub/DVB subtitles (Blu-ray/DVD rips)
are bitmaps, not text - there's nothing for Emby's Stream.vtt conversion
to extract, so a native <track> fundamentally can't render one. Rather
than keep asking Emby's own transcode to burn these in (the exact thing
that kept failing in earlier sessions - missing fontconfig, then an
unrelated "Error starting ffmpeg"), this runs ffmpeg ourselves: a PGS
stream decodes like a second video track, and ffmpeg's `overlay` filter
composites it directly - no text rendering, no libass, no fontconfig
anywhere in this path.

One shared stream per PARTY, not per viewer - explicitly asked for after
the initial plan: every member plugs into the exact same server-emitted
stream, mirroring "host drives, everyone follows" rather than a
per-viewer model. Picking a burn-in subtitle is therefore a host-only,
party-wide choice, like play/pause/next already are.

- server/src/services/TranscodeService.ts (new): one ffmpeg session per
  partyId. getOrStartSession negotiates PlaybackInfo (via the new
  CatalogService.getMediaSource), converts Emby's absolute
  MediaStreams[].Index into ffmpeg's type-relative 0:s:N/0🅰️N
  (absoluteToRelativeIndex - pure, unit-tested), and spawns ffmpeg
  against Emby's own direct/static file endpoint (TODO(verify) - no
  Emby server reachable from this dev environment, see the function's
  own comment). Output is real progressive HLS to a temp dir, served by
  two new routes that poll briefly for the next file. endSession/
  reapIdleSessions handle teardown; PartyService's destroy path and
  advanceQueue both end a party's session immediately, the idle sweep
  is the backstop.
- server/src/services/PartyService.ts: Party/PartyPublicState gain
  burnInSubtitleIndex/burnInAudioIndex (null together = no burn-in);
  advanceQueue clears them (a new item's indices mean nothing on the
  old one).
- server/src/realtime/SocketGateway.ts: new host-only "setBurnInSubtitle"
  handler broadcasting "burnInChanged" - same shape as "next"/
  "itemChanged".
- server/src/services/CatalogService.ts: new getMediaSource() (id/
  container/streams together - what TranscodeService needs); extended
  the local PlaybackInfoResponse type with Container.
- server/src/Logger.ts: new Logger.transcode().
- server/src/index.ts: GET /api/catalog/burn/:partyId/master.m3u8 and
  .../:segment (membership-checked, same pattern as the party REST
  routes); a dedicated idle-reap interval for TranscodeService.
- server/Dockerfile: `apk add ffmpeg` in the runtime stage - no font
  packages needed, unlike Emby's own text-subtitle burn-in.
- client/src/api/party.ts, client/src/api/embyApi.ts: setBurnInSubtitle/
  onBurnInChanged on PartyConnection, burnInStreamUrl().
- client/src/views/player/Player.{html,css,ts}: the subtitle picker's
  image-track options go from unconditionally disabled to host-only
  selectable, labeled to say picking one restarts the stream for
  everyone. Every member (host included) only ever reacts to the
  resulting "burnInChanged" broadcast - never applies a pick
  optimistically, same discipline the rest of the player already uses.
  Audio/quality are disabled while a burn-in is active (one fixed
  encode); a follower's subtitle select is disabled too (nothing left
  for them to meaningfully pick).
- server/test/transcodeService.test.ts (new): absoluteToRelativeIndex,
  session start/reuse/replace, endSession, reapIdleSessions -
  child_process.spawn mocked via a small explicit test seam
  (setSpawnForTesting), never invoking a real ffmpeg binary.
- server/test/socketGateway.test.ts, partyService.test.ts,
  catalogService.test.ts: host-only gating + broadcast for
  setBurnInSubtitle, advanceQueue's reset, toPublicState exposing the
  new fields, getMediaSource.
- docs/architecture.md, README.md: design + an explicit "assumptions to
  verify" note (the direct-source URL shape, first and foremost).

Verified: full typecheck+test+build on both projects (56/56 server
tests). No Emby server or ffmpeg binary is reachable from this dev
environment, so the actual command against a real PGS file is
unverified - flagged explicitly in the docs, same "TODO(verify)" spirit
already used elsewhere in this codebase for an Emby response shape that
can't be checked locally.

c14d0bc08b Replace avatar-click with a request toolbar; add "request resume"
All checks were successful
Publier l'image Docker / test (push) Successful in 25s
Publier l'image Docker / publish (push) Successful in 17s
Asked for directly: a visible bottom toolbar for non-host members
instead of clicking your own small avatar circle (never a very
discoverable affordance), and a second request alongside pause -
"please resume".

- server/src/types.ts, server/src/realtime/SocketGateway.ts: new
  requestResume/resumeRequested, byte-for-byte the same shape and
  handler pattern as requestPause/pauseRequested, independently
  throttled (its own lastResumeRequestUtc - not a shared budget with
  pause). Kept as a plain broadcast signal, same as pause always was -
  no accept/deny state tracked server-side, the host sees the same
  banner/avatar highlight as everyone else and acts with their own
  existing controls.
- client/src/api/party.ts, client/src/types.ts: requestResume() on
  PartyConnection, onResumeRequested callback, a ResumeRequestedMsg type
  (same shape as PauseRequestedMsg, kept separate so a callback's own
  signature says which request it's for).
- client/src/views/player/Player.{html,css,ts}: the avatar is presence-
  only now (no click handler, no "- demander une pause" title) - a new
  .bottomOverlay wraps the request banner, the follower notice, and a
  new .requestToolbar (Demander une pause / Demander une reprise) as one
  flex column, same "stack in normal flow instead of hand-picking a
  pixel offset per box" fix .topOverlay already needed. Pause and resume
  share one showRequestBanner() - they only ever differed by which word
  appears in the banner text. Renamed the shared CSS classes
  (avatarPauseRequested/avatarPauseBadge -> avatarActionRequested/
  avatarRequestBadge) since they're no longer pause-specific.
- server/test/socketGateway.test.ts: new case confirming requestResume's
  throttle is independent from requestPause's own.

Verified against the real compiled bundle: the toolbar shows for a
follower and stays hidden for the host; each button's own client-side
cooldown collapses a rapid double-click to one emission; a pushed
resumeRequested shows the banner with the right text and highlights the
right avatar.

137977893a Render subtitles client-side (<track>) instead of asking Emby to burn them in
All checks were successful
Publier l'image Docker / test (push) Successful in 20s
Publier l'image Docker / publish (push) Successful in 14s
Six rounds of real-server debugging (see docs/architecture.md's player-
track-selection section) found three different, unrelated reasons a
server-side burn-in could fail - missing fonts, a bitmap format libass
fundamentally can't burn, ffmpeg failing outright on an otherwise
unremarkable file - none of which this app's own request ever caused or
could have fixed, all downstream of the one thing every attempt had in
common: asking Emby for a real-time video re-encode. Not needing that
re-encode at all closes the whole class of failure instead of chasing
each one.

- server/src/services/CatalogService.ts: new proxySubtitle asks Emby to
  convert the track to WebVTT (GET /Videos/{id}/{mediaSourceId}/
  Subtitles/{index}/Stream.vtt - a real Emby endpoint their own web
  client already uses for this) - entirely separate from the video
  transcode. applyPlaybackOverrides lost its SubtitleStreamIndex/
  SubtitleMethod=Encode branch - the video request no longer needs to
  know a subtitle was picked at all.
- server/src/types.ts, client/src/types.ts: PlaybackTrackOption's flag
  renamed supportsBurnIn -> isTextBased - same underlying fact (image vs
  text codec), but the name shouldn't keep describing a mechanism this
  app no longer uses.
- server/src/index.ts: new GET /api/catalog/subtitle/:itemId/:subtitleIndex
  route, grouped with the other cookie-authed media-element routes (a
  <track> can't send a bearer header either).
- client/src/api/embyApi.ts: new subtitleUrl(); streamUrl no longer
  carries SubtitleStreamIndex at all.
- client/src/views/player/Player.ts: the subtitle <select> no longer
  reloads the video (reloadWithCurrentOptions, still used for audio/
  quality, never touches subtitles now). New applySubtitleTrack()
  removes/re-adds a fresh <track> and sets video.textTracks[0].mode =
  'showing' synchronously right after appending - deliberately not
  waiting on the <track>'s own "load" event, confirmed against a real
  browser that it doesn't fire reliably at all (a known cross-browser
  quirk), which would have left a subtitle silently never shown - the
  exact symptom this whole saga started from. Re-applied on every video
  (re)load so an audio/quality change (which does still reload the
  video) doesn't drop whatever subtitle was showing.
- server/test/catalogService.test.ts: updated/new cases for
  proxySubtitle and the renamed isTextBased flag; removed the test for
  the now-deleted subtitle-forcing behavior.

Verified against the real compiled bundle: picking a text track adds one
<track> with the right URL and flips it to showing; "Aucun" removes it;
an image-coded track is listed but disabled; changing audio reloads the
video but the subtitle survives it, same element, still showing.

2f670ec9a4 Flag image-based subtitle tracks (PGS/VobSub/DVB) as not burn-in-able
All checks were successful
Publier l'image Docker / test (push) Successful in 22s
Publier l'image Docker / publish (push) Successful in 14s
Two different items both failed the same way when picking a subtitle -
without knowing whether the second one was also a PGS (image/bitmap)
track like the first confirmed one, that result was ambiguous: still the
same known issue, or something new? Rather than keep digging through
server logs per item, this app can just know the answer itself - Emby's
PlaybackInfo response already includes each subtitle stream's Codec.

- server/src/services/CatalogService.ts: getPlaybackOptions reads it and
  reports supportsBurnIn: false for image-based subtitle codecs
  (hdmv_pgs_subtitle/dvd_subtitle/dvb_subtitle - IMAGE_SUBTITLE_CODECS).
  This app forces SubtitleMethod=Encode whenever a subtitle is picked
  (applyPlaybackOverrides), asking ffmpeg's `subtitles` filter (libass)
  to burn it in - libass renders text via a font, it has no path for
  compositing a pre-rendered bitmap at all, confirmed against a real
  server (see docs/architecture.md's Round 4/5).
- server/src/types.ts, client/src/types.ts: PlaybackTrackOption gains
  supportsBurnIn (subtitle tracks only, undefined for audio).
- client/src/views/player/Player.ts: the subtitle <select> now disables
  these options with a "(image, non disponible)" label instead of
  letting anyone pick a track that's guaranteed to break playback -
  listed so it's clear why, not silently missing.
- server/test/catalogService.test.ts: new case covering subrip/ass
  (supportsBurnIn: true) vs hdmv_pgs_subtitle (false) from the same
  MediaStreams response.

a5aca4a823 Fix home page's party "elapsed" label ignoring pauses
All checks were successful
Publier l'image Docker / test (push) Successful in 24s
Publier l'image Docker / publish (push) Successful in 15s
Reported: the time shown for an ongoing party is the movie's elapsed
time. True, but only by coincidence - the label was actually just
Date.now() - party.createdUtc, which climbs at wall-clock speed
regardless of whether the movie is actually playing. Pause it for five
minutes and the home page keeps counting through the pause the player
itself has frozen.

- server/src/types.ts, client/src/types.ts: LobbyPartyDto gains
  positionTicks/isPaused/positionUpdatedUtc - the host's own tracked
  playback state (same values SocketGateway already maintains for their
  party's own room), null for music parties, where there's no single
  "elapsed" across a rotating queue of tracks.
- server/src/realtime/SocketGateway.ts: lobbySnapshot() fills these from
  the host's member record for video parties. Two new broadcastLobby()
  trigger points to keep it reasonably fresh: an actual pause/play
  transition (not every 3s heartbeat resend - same guard already used
  for that transition's log line) and advancing the queue (advanceQueue
  already reset every member's position for the new item; nothing had
  ever pushed that to the lobby before, so a card's title/poster/position
  could sit stale until an unrelated join/leave refreshed it).
- client/src/views/home/Home.ts: updateElapsedLabels() now computes a
  live, pause-aware position for a video party (frozen while paused,
  ticking from position+timestamp while playing) instead of always
  falling back to createdUtc - which is still exactly what a music party
  (or a party missing these fields) uses.
- server/test/socketGateway.test.ts: two new cases - the lobby snapshot's
  video-vs-music shape, and that a transition/next() refreshes it while
  an unchanged heartbeat resend doesn't.

Verified against the real bundled client with a faked "parties" push:
a paused party's label held still across a real wait; a playing one, and
a music party on the unchanged createdUtc path, both kept ticking up.

b2310216ce Fix settings menu visibility bug; make the music player a persistent bar
Some checks failed
Publier l'image Docker / publish (push) Has been skipped
Publier l'image Docker / test (push) Failing after 8s
Fix: player settings menu stuck permanently open
----------------------------------------------
.hide { display: none; } and Player.css's .settingsPanel { display: flex;
... } are both single-class selectors - equal specificity - so whichever
one esbuild happened to bundle later into app.css won the `display`
property on an element carrying both classes. Player.css's own
display:flex always landed after base.css's .hide, so #settingsPanel
showed regardless of the hide class ever being toggled - the toggle logic
itself was correct the whole time, it just had no visible effect.

Fixed at the utility class, not the one call site: `.hide` now uses
`display: none !important`, which wins a same-specificity tie regardless
of bundling order - closes off the whole bug class, since several other
components already set their own `display` for a visible state.

Feature: music player is now a persistent bottom bar, not a page
------------------------------------------------------------------
The music player was its own route (/party/:id -> views/musicPlayer/),
which meant navigating anywhere else - the sidebar, an album to queue up
more tracks - tore the whole thing down (router.ts calls a route's
cleanup, which used to call leaveParty, on every hash change). No way to
browse and listen at the same time.

- client/src/musicBar/MusicBar.ts (new): a Shell-level singleton, mounted
  once into a #musicBar element that's a sibling of #mainContent, never
  touched by route changes. Renders as a fixed bottom bar. Exposes
  initMusicBar/joinMusicParty/leaveMusicParty instead of the router's
  render()-returns-cleanup pattern, since it never registers as a route.
- views/player/Player.ts's dispatcher: a music party no longer renders a
  page - it calls joinMusicParty() and bounces back to /home (a no-op for
  every reachable call site except album's). A video party now calls
  leaveMusicParty() first (harmless no-op if nothing's active) - starting
  or joining a video watch party always leaves the listen party, since
  every party-join call site already funnels through this one dispatcher.
- views/album/Album.ts: the last per-track "start a party" UI now that
  the music player's own inline browse panel is gone (browsing just
  means navigating there normally). Each track's button starts a new
  party or adds to whichever one is already active, decided by
  getActiveMusicPartyId() at CLICK time (not render time) so the action
  taken is always correct even if the label is momentarily stale; every
  button is relabeled in place after a successful click. Starting a
  party from here no longer navigates away at all.
- views/musicPlayer/ deleted entirely (MusicPlayer.ts/.html/.css) -
  superseded by musicBar/.
- Comment updates in global.d.ts/presence.css/trackList.css/party.ts/
  types.ts that named the old module by path.

Verified both fixes by rebuilding and driving the real compiled bundle
through a local static server, with fetch/window.io/window.Hls mocked:
starting a party from an album track leaves the sidebar/page in place and
relabels the other tracks; adding a track posts to the already-active
party's id; navigating into a video party hides the bar, disconnects its
socket, and posts a real leave for the music party before the video
player renders; the settings gear opens/closes correctly for the host in
that same run.

4a31ee741e Rewrite server + client in TypeScript, service-oriented server architecture
All checks were successful
Publier l'image Docker / publish (push) Successful in 18s
Full rewrite, requested directly. Two independent decisions since
TypeScript can't compile itself away at runtime - "no build step" and
"TypeScript" are mutually exclusive, not a small addition to the existing
setup:
- Server: plain tsc (no bundling need - Node resolves its own requires).
  server/dist mirrors server/src 1:1.
- Client: esbuild (does need bundling) - picked over a heavier tool
  (Vite, webpack) since this app's whole client is a couple thousand
  lines; its built-in CSS-from-JS bundling and a `text` loader for
  importing an HTML template as a string cover everything needed via a
  ~30-line hand-written build script (client/build.mjs), not a config
  file for something built for much bigger apps.
Both projects compile independently (no shared-types package - considered
and rejected as more structural commitment than this app's size
justifies; server/src/types.ts and client/src/types.ts have their own
overlapping DTO copies instead). server/'s `npm run dev` uses tsx for a
compile-free dev loop; `npm run build` (tsc) is what server/Dockerfile's
build stage actually runs. client/'s `npm run watch` is esbuild's own
watch mode.

Server: one singleton service class per feature, generalizing the
PartyManager/MusicQueueService pattern that already existed, rather than
route handlers with logic inline:
- AuthService (from embyAuth.js), CatalogService (NEW - previously ~15
  route handlers' worth of Emby queries/DTO shaping inlined directly in
  index.js), PartyService (renamed from PartyManager), MusicQueueService
  (ported as-is, already service-shaped), SocketGateway (from
  socketHandler.js), EmbyClient (from embyProxy.js - low-level plumbing,
  not called a "service" since it has no state/feature of its own).
- index.ts is now thin wiring only: every route reads the session, calls
  one service method, returns the result.
- Real error-handling pass, not just a port: Express 4 doesn't catch a
  rejected Promise from an async handler on its own - a new asyncRoute()
  wrapper + a single error-handling middleware replace what used to be
  zero handling for a request that outright throws. CatalogService
  methods throw a CatalogFetchError (own HTTP status - getRawItem now
  preserves Emby's real 404 instead of a blanket 502) rather than
  touching res directly.

Client: one folder per view (src/views/<name>/<Name>.ts + .html + .css)
instead of one .js file with the markup inline as a template literal. A
view's static shell moved to its .html (esbuild's text loader); per-item
dynamic content (tile grids, episode/track lists) stays as template
-literal-returning functions in the .ts, same as before. Genuinely shared
CSS (tiles, the presence avatar, the series/album detail-header pattern,
track-list rows) lives under src/styles/, imported by whichever views
need it; src/styles/base.css holds the global primitives, imported once
by app.ts. Deliberately not pushed to zero duplication/renaming shared
classes across views for tidiness alone - not worth the risk in a change
already this large. Player.ts keeps its pre-existing internal shape (the
/party/:id dispatcher + the video renderer in one file, importing
renderMusicPlayer from the sibling folder) - that pattern predates this
rewrite and only needed types, not restructuring.

Two real things the port itself caught, not just carried over:
- A type bug: porting SocketGateway's "members" broadcast, reusing
  PartyService's PublicMember interface would have type-checked fine but
  was the wrong (larger) shape - the socket broadcast never included
  isPaused/positionTicks, only the REST response did. Caught by
  comparing against the original JS line by line, fixed with a dedicated
  SocketMemberDto type.
- A real Express+TypeScript friction point: noUncheckedIndexedAccess
  (enabled in both tsconfigs - genuinely useful elsewhere, e.g.
  PartyService.advanceQueue's array indexing) makes every req.params.xxx
  read a type error, since Express's index-signature typing doesn't know
  a matched route's required :name segment is always present. Resolved
  once with a param(req, name) helper rather than 15 routes' worth of
  scattered assertions.

Verified: both projects type-check cleanly in strict mode (tsc --noEmit -
not just "esbuild didn't complain", which it wouldn't even with type
errors present, since it transpiles without checking). Server: every
unit/integration test from the JS version (party lifecycle logging, the
music queue's timer/vote/pause behavior incl. real setTimeout
auto-advance, the socket integration through SocketGateway+PartyService+
MusicQueueService together, the library-type filter, the playback
-override forcing) re-run against the compiled server/dist output -
identical results; the compiled server was actually started and confirmed
listening cleanly. Client: since esbuild bundles everything into one
app.js (no more individually-importable view modules), testing moved to
driving the real compiled bundle through its actual boot -> login ->
router -> view chain (mocked fetch/Socket.IO/hls.js, real clicks/hash
navigation) - arguably more realistic than the old per-module approach.
Confirmed this way: login, the sidebar, home's carousels, a video party
(presence, host controls, leave), the full music hierarchy, a music party
(presence, vote-skip, pause toggle, the inline browse-and-add panel), and
the series page - all through client/dist's actual output, no thrown
errors anywhere.

Not verified: an actual `docker build` of the new multi-stage Dockerfile -
this dev environment has no Docker at all. The build stage runs the exact
npm run build commands already confirmed working locally, just inside
node:20-alpine - the main remaining risk is something environment
-specific, not the build commands themselves, but a real build is still
the first thing to try after this lands.

docs/architecture.md has the full writeup (new "TypeScript and a
service-oriented architecture" section, plus a corrected top-level
"Components" overview that had gone stale even before this change).
