-## Toast notifications, replacing every blocking `alert()`
-
-Asked for directly, prompted by the host-handoff message specifically
-(`"L'hôte précédent a quitté la party - tu es maintenant l'hôte."`) -
-a blocking `alert()` freezes the whole tab and demands a click to
-dismiss, for what's genuinely just a heads-up. Once looking at that
-one, every OTHER `alert()` in the client turned out to be the exact
-same pattern (`alert((err as Error).message)` after a failed
-create/join, or a bare `onError: (message) => alert(message)` on a
-socket connection) - ten call sites total, across `Player.ts`,
-`MusicBar.ts`, `tiles.ts`'s shared `wireTileButtons`, and every one of
-`Home`/`Series`/`Playlist`/`Artist`/`Album`'s own "start a party"
-buttons. All ten now go through one new module instead.
-
-**New `toast.ts`/`toast.css`** - a plain module-level singleton, not
-something Shell.ts mounts like `musicBar/MusicBar` (there's no
-per-party state here, just somewhere to drop text), so it lazily
-creates its own fixed-position container on first use and works from
-literally any file that imports `showToast()`. Visually the same
-light pill/auto-dismiss language `views/player/Player.css`'s own
-`.requestBanner` already used for pause/resume requests, generalized
-to `position: fixed` against the viewport (not `.playerWrap`
-specifically) so it works from any page, stacked (a flex column with
-`gap`, so an error and a moment-later status update don't clobber each
-other) and layered above everything else in the app (`z-index: 100`,
-comfortably clear of the highest anything else currently uses).
-
-**Two variants, one restrained look** - `variant: 'info'` (default,
-the host-handoff message, every status-only case) and `variant:
-'error'` (every migrated `alert()` above) differ by exactly one thing,
-a plain `border-left` accent in `var(--danger)`. Deliberately not a
-red banner/fill even for errors: a failed "start a party" click is
-still just a message, not something this app should suddenly shout
-about - matching the restraint the rest of this app's UI already
-favors (subtle background tints, not loud fills, for e.g.
-`.avatarActionRequested`). No manual dismiss button, same as
-`.requestBanner` before it - every toast fades itself out after
-~4.5s, respecting `prefers-reduced-motion` (an instant show/hide
-instead of the opacity/transform fade, same guard `.spinner` already
-uses elsewhere).
-
-Verified: full `typecheck`/`build` (client only). Confirmed there are
-no `alert(` calls left in `client/src` beyond comments that merely
-mention the word. The fade-in double-`requestAnimationFrame` trick
-(needed because adding the "visible" class in the same frame as the
-insert can get coalesced with it, silently skipping the transition)
-was checked directly against a real element in a real browser rather
-than assumed from the general pattern.
-
-## Library/artist grid: the tile minimum was too wide for a real phone
-
-Reported directly, against a real device: a phone in the
-~360-393px-wide range (an ordinary width, not a rare one) was showing
-exactly one tile per row in every library/artist grid. The grid's
-`minmax(160px, 1fr))` floor was never wrong on its own terms - it's
-just wider than what's left once `.mainContent`'s own side padding is
-subtracted from a real phone's width, and there was no narrower-screen
-override for it at all (unlike the sidebar/nav or the music bar,
-`tiles.css`'s `.grid` had never gotten one).
-
-Fixed with `minmax(clamp(100px, 28vw, 160px), 1fr)` - a fluid minimum,
-not a `max-width` breakpoint. `clamp()` scales continuously with the
-real viewport instead of jumping at one arbitrary width, so every size
-in between "phone" and "desktop" (a tablet, a half-width browser
-window) already gets a reasonable column count too, not just the two
-sizes a breakpoint would have explicitly targeted - and it reduces to
-today's exact `160px` past whatever width `28vw` alone would already
-exceed it, so desktop is provably unchanged rather than just "probably
-fine."
-
-Verified: full `typecheck`/`build` (client only). Confirmed in a real
-browser, not just computed by hand: an `<iframe>` sized to each of
-320/360/375/393/430/768/1200px (an iframe gets its own independent
-viewport for `vw` units, which this sandbox's own unreliable
-`resize_window` emulation can't provide - see the mobile-nav/music-UI
-sections above) with the real compiled `tiles.css` loaded inside it,
-checking the actual rendered column count at each. Every phone width
-from 320 to 393px now gets 2 columns (previously 1), 430px gets 3, and
-768/1200px match what the old fixed `160px` floor already gave -
-confirmed empirically, not assumed from the formula alone.
-
-## The library header wasn't fully sticky: the title still scrolled away
-
-"A sticky search bar" (above) only ever made the `<input>` itself
-sticky - asked for directly again, this time to also keep the page
-title (`.pageHeader`'s `<h1>`) pinned alongside it on `views/library`,
-so both stay visible together while a long grid scrolls underneath
-instead of just the search box.
-
-New `.libraryHeader` wrapper (`views/library/Library.css` - the one
-view of this shape that had no dedicated stylesheet yet, everything
-borrowed from `tiles.css`/`base.css`) around the existing `.pageHeader`
-+ `.searchBar` pair, `position: sticky; top: 0` on the wrapper itself
-with its own opaque `var(--bg)` background - the `<h1>` has none of its
-own, so without this, tiles scrolling underneath would show through the
-title text once stuck. `.searchBar` keeps its own pre-existing
-`position: sticky; top: 0` from `tiles.css` unchanged (still needed as-is
-on `views/artist`/`views/album`, which don't get this wrapper); nested
-inside an already-stuck ancestor that isn't itself scrolling, it's
-inert rather than conflicting.
-
-Scoped to `views/library` only, not `tiles.css`'s shared `.pageHeader` -
-`views/home` uses that same class for a plain, non-sticky title, and
-`views/artist`/`views/album` have since moved to their own hero headers
-(see "Music UI rework" above), not `.pageHeader` at all.
-
-One real collision worth catching: below 720px, `shell/Shell.css`'s own
-`.mobileTopBar` is *also* `position: sticky; top: 0` (the app's brand
-bar, sitting above `.mainContent` as a sibling, not an ancestor) - the
-pre-existing sticky `.searchBar` already raced it for the same spot,
-just narrowly enough (one slim input) not to get reported. Stacking a
-whole title+search block at `top: 0` too would have properly covered
-it, later in paint order. `.mobileTopBar` got an explicit
-`height: var(--mobile-topbar-h)` (new `base.css` token, `49px` -
-replacing its previous padding-derived auto height with a fixed one
-anything else can reliably stack against), and `.libraryHeader` sticks
-to `top: var(--mobile-topbar-h)` instead of `0` under that same 720px
-breakpoint - directly below the brand bar instead of underneath it.
-
-Verified: full `typecheck`/`build` (client only). No Emby session is
-needed to see either state, so checked directly: real compiled
-`app.css` loaded (same-origin, from the running dev server) into two
-`<iframe>`s - 1000px and 375px wide, each its own independent viewport
-for the 720px media query, the same workaround this sandbox's own
-broken `resize_window` emulation has needed all session - reproducing
-`Shell.html`'s `.mobileTopBar`/`.mainContent` plus `Library.html`'s new
-markup and a couple dozen dummy tiles, then scrolled deep into the grid
-in both and read `getBoundingClientRect()` back: on the 1000px frame
-the title and search bar both stayed at the viewport top, tiles
-scrolling underneath, opaque background confirmed; on the 375px frame
-`.libraryHeader`'s top edge landed exactly at `.mobileTopBar`'s bottom
-edge (49px) with zero overlap, both bars' text still visible together.
-
-## Alphabet index: jump straight to a letter in a library
-
-Asked for directly, alongside the sticky header above: a way to jump to
-a letter instead of scrolling a long library by hand. Proposed two
-mockups first (a right-edge A-Z rail either bare or paired with sticky
-per-letter section headings, both with the drag-to-scrub-plus-big-letter-
-bubble feel of iOS's own Contacts index) - the section-headings version
-was picked.
-
-New `alphaIndex.ts`, deliberately not folded into `tiles.ts`: it's a
-`views/library`-only concern (the ask was specifically "dans les
-bibliothèques"), and `tiles.ts` stays exactly what every other page
-still wants - one flat, ungrouped grid.
-
-**Grouping** buckets each item by its first letter, accents folded to
-their base (`normalize('NFD')` + stripping the combining marks) so
-"Écho" lands under "E" like a French speaker would expect, not off in
-its own accent-specific bucket. No client-side re-sort needed -
-`embyApi`'s `getLibraryItems`/`getArtists` both already ask Emby for
-`SortBy: SortName`, so a run of same-bucket items is already contiguous.
-
-**Layout**: a `.letterHeading` (`grid-column: 1 / -1`) inserted before
-each new bucket, directly inside the *same* `.grid` tiles.ts's own tiles
-already populate - not a separate mini-grid per letter, which would have
-needed its own column-count logic duplicated 20+ times over. Its `top`
-(both for its own `position: sticky` and as every jump target's
-`scroll-margin-top`, so a jump doesn't land a heading half-hidden behind
-the still-stuck header above it) is measured off `.libraryHeader` at
-runtime - `getComputedStyle(libraryHeader).top` picks up whichever of
-Library.css's two breakpoint values (`0` desktop, `--mobile-topbar-h`
-mobile - see the sticky-header section above) is currently active
-without this module needing to know that breakpoint exists at all.
-
-`renderGroupedTilesInChunks` mirrors `renderTilesInChunks`'s own chunked
-`insertAdjacentHTML` (see that function's comment - a real library can
-run past a thousand items, and one synchronous `innerHTML` write for all
-of them is exactly the "front freezes while it loads" failure this app
-already fixed once elsewhere); a chunk boundary landing mid-bucket is
-harmless, headings and tiles just interleave in whatever order they're
-inserted.
-
-**The rail** (`.alphaRail`, fixed to the right edge) is 27 buckets
-(`#` + A-Z), each dimmed and inert if `items` has nothing in it. Tap or
-drag it - `pointerdown`/`move`/`up` on one dedicated element with
-`touch-action: none` and `setPointerCapture`, the identical shape
-`shell/Shell.ts`'s own nav-sheet drag handle already uses - and a
-center-screen bubble shows the current letter while dragging, the same
-"big transient label during a drag" idea as that handle's own gesture,
-applied here to a very different one. Scrolling normally (not
-dragging) instead runs a small scroll-spy on `window`'s scroll event,
-highlighting whichever bucket's heading is currently at the top.
-
-Both the rail and every heading's sticky offset track two elements'
-*real* rendered size rather than a guessed constant - a `ResizeObserver`
-on `.libraryHeader` (a very long title could wrap to two lines) and on
-`shell/Shell.html`'s `.bottomStack` (the music bar floats there whenever
-a listen party is active, on desktop as well as mobile, and can
-start/stop while this page stays open) - so the rail's own `bottom`
-always stops exactly above whichever of those is currently showing,
-instead of a listen party's music bar quietly covering "X"-"Z".
-
-**Search** still uses tiles.ts's existing `wireSearchFilter` unchanged
-(`.tile`-level show/hide) - `wireSectionSearchSync` just walks each
-`.letterHeading`'s following siblings up to the next one and hides it
-too if every tile in that run is now `.hide`'d, registered on the same
-input *after* `wireSearchFilter` so it always sees the up-to-date
-`.hide` state (same-element listener order = registration order).
-Without it, searching down to matches in one bucket would leave every
-other bucket's heading floating above nothing.
-
-**Cleanup**: `renderLibrary` itself had to change shape - from a plain
-`async function` to the synchronous-wrapper-around-an-async-IIFE
-`views/player/Player.ts`'s `renderPartyPlayer` already uses, returning
-a real `CleanupFn` (see router.ts) instead of the `Promise<void>` an
-`async function` can't help but return. Both the rail's two
-`ResizeObserver`s and its `window` scroll/resize listeners live past
-whatever DOM `router.ts`'s next `innerHTML = ''` clears, so without an
-explicit teardown they'd keep running (and, for the scroll listener,
-keep doing real work) after leaving the page - the exact leak class
-"Realtime transport" up above already covers this app getting bitten by
-once.
-
-Verified: full `typecheck`/`build` (client only). No Emby session
-available here, so the interaction itself was checked by bundling
-`alphaIndex.ts` alone (a throwaway esbuild entry point, deleted after)
-into a synthetic page reproducing the real Shell/Library DOM and real
-compiled CSS, then driven for real rather than assumed: a genuine
-browser click on a rail letter (not a script-dispatched one - dispatched
-`PointerEvent`s never register as an active pointer, so `setPointerCapture`
-itself only ever proved out under real input) jumped and highlighted
-correctly with zero console errors; dragging across several letters
-updated the active one and the bubble live at each step; tapping an
-empty letter highlighted it but left scroll position untouched; typing
-into the search box hid exactly the buckets left with no visible tiles
-and none of the others; growing `#musicBar`'s height live moved the
-rail's bottom edge with it and back; and calling the returned cleanup
-stopped that last reaction cold, confirming the observer was actually
-disconnected rather than just idle.
-
-## The alphabet index's headers were in the wrong order
-
-Reported directly, against a real library: header letters coming out
-as e.g. `A, B, T, B, L` instead of one run per letter in order. Not a
-sorting bug in Emby, and not a bug in `renderGroupedTilesInChunks`'s own
-"new bucket = new heading" logic either - both were already correct.
-The actual mismatch: `getLibraryItems`/`getArtists` ask Emby to *order*
-the array by `SortBy: SortName`, but never asked for each item's
-`SortName` *value* back, so `alphaIndex.ts`'s `bucketFor` had nothing to
-bucket by except the raw display `name` - and Emby's `SortName` strips
-leading articles ("The", "Le", "L'", ...) for exactly the kind of
-natural alphabetical browsing this index is for. An item like "The
-Bunker" sorts (correctly) among the B's by Emby's own SortName, but
-bucketing it by its literal display name instead computed "T" - a
-spurious heading mid-run, immediately followed by a second, duplicate
-"B" heading once the next real B-titled item came right back around.
-Every other letter, with no such item, looked completely fine, which is
-why this wasn't caught by the earlier synthetic verification (its fake
-titles never happened to include an article-stripped one at all).
-
-Fixed at the source instead of trying to reimplement Emby's own
-article-stripping rules client-side (which language's articles, and
-which are configurable server-side, isn't this app's business to know):
-`getLibraryItems`/`getArtists` now also request `Fields: SortName`, new
-`ItemDto.sortName` carries it through (falling back to `name` when a
-caller doesn't request it - same "populated where it matters, harmless
-default elsewhere" shape `durationTicks`/`indexNumber` already use), and
-`alphaIndex.ts` buckets by *that*, not `name`. Bucketing by the exact
-same key Emby used to order the array is what guarantees a bucket is
-always one contiguous run - not bucketing by something that's usually
-close enough.
-
-Verified: full `typecheck`/`test`/`build` on both projects (147/147
-server tests). Reproduced the exact reported shape first - a small
-fake item list in Emby's own SortName order, one entry's display name
-starting with a different letter than its `sortName` (`"The Bunker"`,
-`sortName: "Bunker"`, positioned between two other B titles) - confirmed
-it produced the same `A, B, T, B, L` heading sequence against the old
-bucket-by-`name` code, then confirmed the fix collapses it to the
-correct `A, B, L` against the exact same input.
-
-## The music bar's queue popup: broken on desktop, unclosable on mobile
-
-Two reports that turned out to be the same missing `position` rule.
-`.musicBarQueue`'s own comment already said it should "pop up ABOVE the
-bar" (like `Player.css`'s `.settingsPanel` above its gear button), but
-the CSS itself never actually gave it a `position` on desktop at all -
-a plain normal-flow block, first child of `.musicBar`. Toggling it
-visible didn't float anything; it pushed `#musicBarPanel` (the actual
-transport controls) out of the way, growing `.bottomStack`'s own
-fixed-to-viewport box from the bottom up - reported directly as the
-player looking broken the moment the queue was opened.
-
-Mobile had a different-looking but related bug. `#musicBarPanel`
-becomes a full-screen `position: fixed` overlay under 720px; a normal-
-flow `.musicBarQueue` sibling would have rendered *behind* it, so it
-had already been given `position: relative; z-index: 26` specifically
-to still show on top once opened from inside that full-screen panel
-(see the git history for that rule's own reasoning). That's a real fix
-for visibility, but not for layout: `position: relative` leaves an
-element sized and placed by normal flow, which put the queue somewhere
-in the middle of the screen rather than covering it - directly
-overlapping the very `#toggleQueueBtn` used to open it, the only way
-that existed to close it again. Reported directly as "can't be closed."
-
-Fixed with a `position` on both sides, matching each context's actual
-shape - `.musicBar` gets `position: relative` (a containing block),
-desktop's `.musicBarQueue` becomes `position: absolute; left: 0;
-right: 0; bottom: 100%` (floats directly above the bar, out of normal
-flow, without touching `#musicBarPanel`'s own layout at all), and
-mobile's becomes `position: fixed; inset: 0` (a proper full-screen
-overlay of its own, `max-height: none` overriding the base rule's
-`50vh` so it isn't clipped) - the same "size for what this context
-actually needs" as `#musicBarPanel`'s own fixed/inset:0 treatment right
-next to it.
-
-Also added, so closing it never again depends on precisely where the
-toggle button happens to render underneath: a dedicated `#queueCloseBtn`
-inside the queue's own header, plus a click-outside-closes listener on
-`document` (`views/player/Player.ts`'s own `settingsPanel` pattern) for
-the desktop popover case.
-
-Verified: full `typecheck`/`build` (client only). No Emby session here,
-so checked directly - `initMusicBar` called against a synthetic
-`.bottomStack`/`#musicBar` reproducing the real Shell markup, real
-compiled CSS, a fake queue list: on the (real, 1280px) desktop viewport,
-opening the queue landed its bottom edge exactly on the bar's own top
-edge (zero gap, zero overlap) without moving the bar at all, and both
-the close button and a click on unrelated page content behind it closed
-it correctly. On a 375px-wide `<iframe>` (this sandbox's own
-`resize_window` viewport emulation is unreliable - see the mobile-nav/
-music-UI/library-grid sections above), with the now-playing panel
-opened first: the queue rendered as a genuine full-viewport overlay,
-`elementFromPoint` at the close button's own center hit the close button
-itself (not something on top of it), and closing the queue correctly
-returned to the still-open now-playing panel rather than closing
-everything.
-
-## Library tile buttons rendering on top of the sticky header
-
-Reported directly: scrolling a library, a tile's own action buttons
-("Lancer une watch party" / "Voir sur Emby") would briefly render
-*above* the sticky title+search header instead of scrolling behind it.
-
-Both `.libraryHeader` and the alphabet index's `.letterHeading` were
-`z-index: 2` - copied from `tiles.css`'s own pre-existing `.searchBar`,
-sticky at that same value long before either of them existed. What
-that copy missed: a tile's own `.tileOverlay` (its hover-revealed
-action buttons - always-visible rather than hover-revealed on a touch
-device, see `tiles.css`'s `(hover: none)` block) is *also* `z-index: 2`.
-Equal z-index is a tie, and a tie breaks toward whichever renders later
-in the DOM - a tile, inside `#grid`, always after the header. The
-original slim `.searchBar` never showed this in practice (a single
-input has little vertical range to actually overlap a scrolling tile
-during the transition); wrapping it into the much taller
-`.libraryHeader` gave a scrolling tile far more room to pass directly
-underneath before fully clearing it, is what actually surfaced it.
-
-Fixed by raising `.libraryHeader` and `.letterHeading` to `z-index: 3`
-- comfortably clear of `.tileOverlay`'s 2, and matching
-`shell/Shell.css`'s own `.mobileTopBar` (the other sticky header
-`.libraryHeader` already has to stack correctly under on mobile).
-
-Verified: full `typecheck`/`build` (client only). Confirmed as a real
-regression, not just reasoned about - real compiled CSS loaded into a
-page reproducing `.libraryHeader` + a real `.grid` of tiles (their
-`.tileOverlay` forced visible, simulating a touch device), scrolled so
-a tile genuinely overlapped the header's own rect, then
-`elementsFromPoint` read the actual paint order at that point: with
-the header's z-index forced back to the old `2`, `.tileOverlay` topped
-the stack exactly as reported; restored to `3`, the header (and the
-search input inside it) topped it instead, `.tileOverlay` three layers
-down, unreachable.
-
-## The music bar's compact layout: the progress bar was never actually full-width
-
-Reported directly, again, after the queue-popup fix above - the desktop
-bar still didn't look right: the progress bar needed to span the full
-width, with everything else in one row underneath.
-
-`.musicBarProgressTrack`'s own comment already described it as "a thin
-strip along the bar's own top edge" - the intent was always a full-width
-strip above a row of controls, mirroring Spotify/YouTube Music's own
-compact players. But `#trackProgress` (that element) is `.musicBarPanel`'s
-*first* child inside a 3-column grid (`.musicBarPanelTrack`/
-`.musicBarPanelTransport`/`.musicBarPanelSide`), with no `grid-column`
-of its own - so grid auto-placement dropped it into column 1 of row 1
-like any other item, squeezing it to that column's own width and
-wrapping `.musicBarPanelSide` onto a second row underneath it instead.
-Easy to miss at a glance: with no track loaded, `.musicBarPanelTrack`'s
-own content (a small image + short placeholder text) still left column
-1 wide enough that the squeeze didn't look obviously broken - see the
-queue-popup section above for the *other* half of "cassé en desktop",
-found and fixed first without this one.
-
-Fixed with one line: `.musicBarProgressTrack { grid-column: 1 / -1; }`.
-Spanning all 3 columns in row 1 is what pushes every sibling after it
-(auto-placed, no changes needed to any of them) into row 2, across the
-full width - track/transport/side exactly where the 3-column rule
-already intended them, just no longer sharing row 1 with the progress
-bar.
-
-Verified: full `typecheck`/`build` (client only). Checked directly - a
-synthetic page with real compiled CSS, `initMusicBar` called against a
-reproduction of the real Shell markup, a fake track's name/artist/
-position set so `.musicBarPanelTrack` has realistic content width. Read
-back with `getBoundingClientRect()`: the progress bar's own width
-matched `.musicBarPanel`'s full content width exactly (not the viewport,
-which include its own outer padding); its bottom edge sat at or above
-every other row's top edge; and the other three elements' vertical
-ranges genuinely overlapped each other (not just similar `top` values,
-which `align-items: center` legitimately varies by each one's own
-content height) - confirming one shared row below, in the original
-track/transport/side left-to-right order.
-
-## An album's track rows collapsed to 3 lines on mobile for no reason
-
-Reported directly: there was room to fit an album's track rows
-(index/name/duration/a small play-or-queue button) on one line on
-mobile, but `trackList.css`'s own `@media (max-width: 600px)` forced
-`.trackRow` down to a 2-column grid and pinned both `.trackDuration`
-and the button to that same second column - auto-placement then
-stacked the two of them into their own rows underneath the track name,
-three rows total instead of one.
-
-Removed outright rather than tuned - the numbers don't support it
-having ever been needed. `.trackRow`'s fixed overhead (28px index +
-2×12px gaps + `auto`-sized duration/button + `12px` horizontal padding)
-comes to roughly 155-165px, and even the narrowest common phone width
-(320px) leaves comfortably more than that for `.mainContent`'s own
-side padding plus a `1fr` name column - `.trackName`'s existing
-`text-overflow: ellipsis` was already doing exactly the job this
-breakpoint assumed it couldn't.
-
-Verified: full `typecheck`/`build` (client only). Checked directly, not
-assumed: real compiled CSS, a handful of `.trackRow`s (short and
-deliberately overlong names) loaded into two `<iframe>`s at 320px and
-375px - this sandbox's own `resize_window` viewport emulation is
-unreliable, see the mobile-nav/music-UI sections above. At both widths
-every row's index/name/duration/button sat on one line (their vertical
-ranges genuinely overlapping, not just similar by coincidence), left to
-right in that order, with the long names confirmed actually truncated
-(`scrollWidth > clientWidth`) rather than merely happening to fit.
-
-## A mobile install nudge for the PWA
-
-Asked for directly: the PWA (see "Progressive Web App" above) existed,
-but nothing ever told a mobile visitor it could be installed at all -
-Chrome's own default mini-infobar is easy to miss/dismiss, and Safari
-has no browser-driven prompt whatsoever.
-
-New `pwaInstall.ts`, self-mounting like `toast.ts` (no per-route/
-per-party state to attach) but with one real difference from that
-module's own lazy-init pattern: `beforeinstallprompt` (Chrome/Edge/
-Android WebView's event for this - not in `lib.dom.d.ts`, Safari/
-Firefox never implement it) can fire before any UI exists to react to
-it, and the browser never replays it for a listener that attached too
-late. The listener itself is a top-level side effect of importing the
-module - `shell/Shell.ts` does that (and calls the module's own
-`initPwaInstallPrompt()`, after `initMusicBar`), and since ES module
-imports all evaluate before an entry file's own top-level code runs,
-that listener is live well before `app.ts`'s `boot()` even starts its
-async login check, regardless of how soon the event actually fires.
-
-Two real install paths exist, and the banner speaks to whichever one
-applies:
-- **Chrome/Edge/Android WebView**: `event.preventDefault()` stashes the
-  captured event (this banner replaces the browser's own default one);
-  clicking "Installer" calls the real `prompt()` and reads back
-  `userChoice` - only an outright 'accepted' removes the banner, since
-  the picker's own 'dismissed' just means "not right now", not "stop
-  asking" (that's what the banner's own close button is for).
-- **iOS Safari**: no such event exists at all, ever - detected instead
-  by user-agent sniffing (there's no clean feature-detection for "is
-  this iOS Safari"), showing manual instructions ("appuie sur Partager
-  puis Sur l'écran d'accueil") with no button, since there's nothing to
-  programmatically trigger.
-
-Mobile-only (`matchMedia('(max-width: 720px)')`, this app's own
-existing breakpoint, re-checked on resize for a live rotate/unfold) and
-suppressed entirely once already running installed
-(`display-mode: standalone`, or `navigator.standalone` for iOS Safari's
-own equivalent flag, which has no `display-mode` query at all). A
-close click remembers "don't ask again" in `localStorage` - not
-re-shown even against a fresh `beforeinstallprompt` on a later visit.
-
-Rendered as a plain normal-flow banner at the very top of `<body>`,
-before `#app` - not a fixed/sticky overlay - specifically to avoid
-needing to coordinate yet another offset with `shell/Shell.css`'s own
-already-stacked `.mobileTopBar`/`.libraryHeader` pair (see the sticky-
-header sections above) or `alphaIndex.css`'s rail. It simply pushes the
-app down by its own height and scrolls away with the page, the same as
-a browser's own native install infobar would.
-
-Verified: full `typecheck`/`build` (client only). No real device
-install flow is triggerable in this sandbox (nothing can fabricate a
-genuine browser installability signal), so checked everything around
-that boundary directly instead: a synthetic `beforeinstallprompt`-
-shaped event (real `Event`, stubbed `prompt`/`userChoice`) dispatched
-into real compiled CSS/JS confirmed the banner appears with the
-install button, that button calls the stub `prompt()` and removes the
-banner only on an 'accepted' outcome, and that the close button both
-removes it and blocks a *second* dispatched event from reopening it.
-Overriding `navigator.userAgent` to an iPhone string confirmed the
-iOS-flavored copy with no install button. A same-event dispatch into a
-real ≥900px-wide `<iframe>` confirmed the banner never renders there
-at all, regardless of the event firing.
-
-## OS-level media controls (Windows' SMTC, macOS' Now Playing, ...)
-
-Asked for directly: linking whatever's playing to Windows' own media
-popup (the one media keys/the volume flyout show) - the standard
-Media Session API (`navigator.mediaSession`), which the same code path
-also surfaces to macOS' Now Playing widget and Android's notification
-for free, on whichever OS/browser combination actually implements it
-(Chromium family; Firefox has never implemented it at all).
-
-New `mediaSession.ts`, a thin wrapper - every export is a one-line
-`'mediaSession' in navigator` guard around the exact browser call, not
-a new abstraction of its own - shared by `views/player/Player.ts`
-(video) and `musicBar/MusicBar.ts` (a listen party), which can never
-both be active at once (starting/joining either already leaves the
-other first - see docs above), so there's no risk of the two fighting
-over this one global.
-
-**Metadata/position/playback state** hook into each player's own
-existing single-source-of-truth functions rather than adding parallel
-call sites everywhere: Player.ts's `updatePlayPauseBtn`/
-`updateProgressBar` (already the one place `#playPauseBtn`'s icon and
-the seek bar's fill/label get synced, from every driver-changed event,
-the heartbeat, and the ticker alike) also call
-`setMediaSessionPlaybackState`/`setMediaSessionPositionState` now;
-MusicBar.ts's `setPlayIcon`/`updatePositionDisplay` do the same. Title/
-artwork update at both places an item/track actually changes
-(Player.ts's `init`/`onItemChanged`, MusicBar.ts's `loadTrack`) -
-artist/album are left empty for video (meaningless there, same as this
-app's own UI already treats them).
-
-**Play/pause/seek** are wired once per party (not re-wired on state
-changes) via `setMediaSessionActionHandlers` - the handler functions
-themselves close over local state (`isHost`, `conn`, ...) and read it
-fresh on every OS-triggered call, the same way any other closure in
-either file already does, so a handler set at party-join time keeps
-working correctly straight through a live host handoff without needing
-to know that happened. Two real permission models, unchanged by this:
-video's play/pause is host-only - a non-host's OS-level play/pause
-routes to the exact same `requestPause`/`requestResume` (now factored
-out so both the in-page buttons and this can call them) the request
-toolbar already uses, never touching the video directly - and seeking
-is gated on `isHost` the same way the in-page seek bar already is
-(factored into a shared `seekTo`, reused by both the pointer handler
-and this). Music has neither gate (no host concept at all - see
-MusicQueueService's own reasoning), so its handlers act directly.
-
-**"Next"** is handled differently from play/pause/seek because a
-*registered* `nexttrack` handler is what makes the OS show that
-control at all, regardless of whether clicking it would currently do
-anything - so unlike the other three, its presence has to track
-whatever the in-page equivalent's own visibility already tracks, via a
-separate `setMediaSessionNextAction(fn | null)` called alongside it:
-Player.ts's `#nextBtn` (`isHost && hasNextQueued`, in `becomeHost` and
-`onItemChanged`) and MusicBar.ts's vote-skip button (`music.current`,
-in `applyMusicState` - clicking the OS's own "next" casts one skip
-vote, same as the in-page button, not an instant skip).
-
-**Clearing**: `clearMediaSession()` (metadata, playback state, *and*
-every action handler) runs on Player.ts's route cleanup and
-MusicBar.ts's `leaveMusicParty` - an OS-level "now playing" card that
-outlives the actual party would be actively wrong, not stale. A
-lighter `setMediaSessionIdle()` (metadata/state only, action handlers
-left alone) covers MusicBar.ts's own "queue ran empty but still in the
-party" case instead - play/pause/seek stay meaningful the instant
-something plays again, so there's nothing to re-wire there.
-
-Verified: full `typecheck`/`build` (client only). `mediaSession.ts`
-itself checked directly against the real API in a real Chromium
-browser (this sandbox's own): metadata resolves to a genuine
-`MediaMetadata` with the right fields and a resolved artwork URL (or
-none for an empty one), playback state and position state both apply
-without throwing, an invalid (non-positive/`NaN`) duration is silently
-skipped rather than reaching the browser call that would throw on it,
-action-handler registration doesn't throw with or without `onSeek`
-supplied, and both `setMediaSessionIdle`/`clearMediaSession` reset
-metadata to `null` and playback state to `'none'`. Player.ts's/
-MusicBar.ts's own wiring is one-line calls into already-verified
-functions at points each file already treats as its single source of
-truth for that piece of state (see above) - not independently
-exercised end to end against a live party (would need mocking the
-entire socket/party layer for no more real signal than reading the
-call sites already gives), and the actual OS-level popup itself - the
-whole point - isn't something this sandbox can display or click
-regardless. Worth a real Windows/Chrome check once deployed.
-
-## Device takeover: both devices "on the session", neither one's controls working
-
-Reported directly: switching a watch/listen party from one device to
-another left both devices looking active, with no controls actually
-transferring. The device-takeover mechanism itself - `SocketGateway`'s
-"join" handler force-disconnecting the old device's socket once the new
-one confirms - was already correct and already guarded against the
-obvious failure mode (its own comment on the "leave"/"disconnect"
-handlers: a stale connection's own eventual disconnect must not be
-mistaken for a real leave). The actual bug was two gaps *around* that,
-neither in the takeover mechanism itself.
-
-**Gap 1 - the old device never reacted to being kicked.** Both
-`Player.ts` and `MusicBar.ts` wired `onClose: () => {}` - a complete
-no-op - to the connection's "disconnect" event. So the moment a takeover
-force-disconnected the old device's socket, that device's own video/
-hls.js instance (or the persistent music bar) just kept running exactly
-as before: the socket was dead, but nothing told the local `<video>`/
-`<audio>` to stop, and nothing navigated away or reset `isHost`. From
-the old device's own screen, everything still looked (and for local-only
-playback, sounded) fully live - exactly "both devices on the session."
-Fixed: both now react to an *unprompted* close (one that didn't already
-run this route/module's own explicit teardown - `leftIntentionally` in
-Player.ts, `activePartyId` already being null in MusicBar.ts, both set
-synchronously by that explicit teardown well before the async
-"disconnect" this checks against ever arrives) by tearing down local
-playback and leaving, the same as if the user had clicked "Quitter"
-there themselves.
-
-**Gap 2 - reacting to the kick had no safe way to do that.** The obvious
-fix for gap 1 - call the same leave path "Quitter" already uses - ran
-straight into a second, worse bug: `POST /api/parties/:partyId/leave`
-removes a member by `userId` alone, with no equivalent of the socket
-handlers' own staleness guard (there's no live connection for a REST
-call to compare against). Calling it from the *old*, superseded device
-would have ended the *new* device's membership too - silently undoing
-the takeover it was supposed to be cleaning up after. Fixed by giving
-this route the same guard via `deviceId` instead of a socket reference:
-new `PartyService.isStaleDevice(member, deviceId)`, and `leaveParty()`
-(client) now sends its own `getDeviceId()` for the server to compare.
-Only ever blocks on positive evidence of a mismatch - a member with no
-recorded deviceId yet, or a caller that sent none, still leaves exactly
-as before this existed.
-
-Verified: full `typecheck`/`test`/`build` on both projects (153/153
-server tests - new coverage for `isStaleDevice` covering a matching
-deviceId, a mismatched one, an unset member deviceId, an unset caller
-deviceId, and an unknown member, each checked against the *reason* it
-should or shouldn't block, not just the outcome). The client-side
-onClose fix was checked against the exact reported scenario, not just
-reasoned about: a fake `io()` standing in for Socket.IO (real `.on`/
-`.emit`/a scriptable `.disconnect()` that fires real listeners) let
-`joinMusicParty`/`leaveMusicParty` run for real. Firing `disconnect`
-right after a real `leaveMusicParty()` call produced no toast and left
-the bar hidden (no spurious "connection lost" message on an intentional
-leave); firing it with no prior leave - the takeover-kick shape -
-produced the "Connexion à la party interrompue" toast and correctly
-tore the bar down. Player.ts's own `leftIntentionally` fix mirrors this
-exact shape (confirmed by reading, not re-verified with a second live
-harness - hls.js/a full player DOM would need mocking for no more
-signal than the MusicBar case already gives, given both share the same
-logic shape end to end).
-
-## A track started directly never fell back to its album's artwork
-
-Reported directly: the app struggles to find artist/album/track images.
-Traced one concrete, confirmed cause: `imageUrlFor`'s own
-`Audio -> AlbumId` fallback (added earlier specifically because a track
-essentially never has its own Primary image, only its album usually
-does) was silently never triggering for a track played directly - not
-via its album or artist - because the raw item that decision runs
-against, `CatalogService.getRawItem`, never requested `AlbumId` from
-Emby in the first place. Emby's default field set for a single-item GET
-omits it entirely, so `item.AlbumId` read `undefined` there regardless
-of whether the track's actual album genuinely had one - `imageUrlFor`
-fell through to the track's own id every time, for every party started
-this way.
-
-Every OTHER path that resolves a track's image already asks for it
-correctly - `getAlbumTracks`/`getPlaylistItemsRaw` both already include
-`AlbumId` in their own `Fields`, which is why launching a whole album/
-artist/playlist, or a queue built from one, was never affected. Fixed
-the one gap instead of guessing at a broader rewrite: `getRawItem` now
-requests `Fields=AlbumId` too. Harmless for every non-Audio item it also
-fetches (Movie/Series/Episode/...) - Emby just omits a field that
-genuinely doesn't apply to them.
-
-Not the whole story, most likely - a real Emby library can also
-legitimately have no Primary image at all for a given artist or album
-(nothing for this app to fall back to, no bug to fix), and this fix
-only ever covers the one specific path (a track started directly) that
-was provably missing a field it needed. Flagged directly rather than
-overclaiming "images are fixed" - worth another, more specific report
-(which item exactly, from where) if artist/album art still struggles
-after this.
-
-Verified: full `typecheck`/`test`/`build` (server only - `CatalogService.ts`
-is server-side). New test confirms `getRawItem`'s actual outgoing
-request includes `Fields=AlbumId` (a mocked `EmbyClient.fetch` capturing
-the real path/query it was called with, not just asserting on the
-already-separately-tested `imageUrlFor` logic downstream of it).
-
-## The music bar's mobile now-playing screen didn't fit landscape
-
-Reported directly, along with a fair general complaint: the mobile
-now-playing overlay used mostly fixed sizes, and the one that mattered
-most - the album art - was sized off `vw` (`min(220px, 60vw)`), the
-viewport dimension a phone in landscape has *plenty* of. Stacked
-vertically (art, then text, then the transport row, then the side row)
-with that same art staying pinned near its 220px cap regardless of how
-little vertical room was actually left, the screen ran well past a
-typical landscape phone's height and needed to scroll to reach the
-transport controls - not adapted to the rotation at all.
-
-Fixed with a dedicated `@media (max-width: 720px) and
-(orientation: landscape)` block, not by chasing every fixed value in
-the portrait rules: the art moves beside the title/artist instead of
-above them (`.musicBarPanelTrack` becomes `flex-direction: row`),
-freeing most of the vertical space the portrait layout spends stacking
-them - and every size that actually needs to respond to the rotation is
-now capped by `vh` (`min(120px, 20vh)`), the dimension landscape
-actually constrains, instead of `vw`. A few fixed margins shrink
-alongside it in this same block, same reasoning: adapting to less
-vertical room, not arbitrary tightening.
-
-Deliberately NOT changed: `.musicBarPlayBig`'s 56px transport button
-and the other icon buttons. A touch target's size answers to a
-finger, not the screen - shrinking it in landscape to "adapt" would
-trade a real usability problem (nothing to tap accurately) for a
-cosmetic one, the opposite of the actual ask.
-
-Verified: full `typecheck`/`build` (client only). Checked directly, not
-just reasoned about - real compiled CSS with the real markup loaded
-into `<iframe>`s sized to a wide (700x320) and a deliberately extreme,
-narrow (650x280) landscape shape (this sandbox's own `resize_window`
-viewport emulation doesn't reflect orientation reliably - iframes do,
-same workaround as every other viewport-shaped check this session).
-Both matched `(orientation: landscape)`, both switched
-`.musicBarPanelTrack` to a real `row` layout with the art measurably to
-the image's left, both image sizes tracked the shrinking `vh` cap
-correctly (64px/56px respectively, not the old fixed 220px), and both
-fit their entire content within the viewport's own height with zero
-overflow - even the extreme 280px-tall case, which the pre-fix numbers
-would have overflowed by well over 200px. A separate portrait check
-(375x700) confirmed this landscape block changes nothing there: still
-`column`, still the original 220px `vw`-capped art, unaffected.

-## Static (persistent) watch parties
-
-Asked for directly: a watch party built from a whole series or video
-playlist that remembers the group's progress *and* each person's, so
-someone coming back or joining late sees what they missed. Full design
-in [`spec/static-watch-party.md`](../spec/static-watch-party.md). The
-short version:
-
-- **A new persistent entity, not a change to Party.**
-  `StaticPartyService` owns the group and member progress. Each session
-  is an ordinary live `Party` linked back through `party.staticLink`,
-  so the player, sync, shared stream, lobby and host handoff are all
-  reused unchanged. `PartyService` calls into `StaticPartyService`,
-  never the other way around.
-- **This app's first on-disk state.** One JSON file per static party
-  (`StaticPartyStore`, `${DATA_DIR}/static-parties/<id>.json`). Writes
-  are atomic, debounced per party, and flushed on SIGTERM. It started
-  as a single file for every party; that was split, so a write only
-  touches the party that changed and a corrupt file costs only that
-  party. The old single file is migrated once, on first load. "Party
-  lifecycle" above still holds for ordinary parties.
-- **Its own tab and its own name.** The UI calls these **Lounge
-  parties**, next to **Watch party** (classic video) and **Listen
-  party** (classic audio). The code keeps "static party". The "Lounge
-  parties" tab (`/static`) lists them. The home page's live "Parties en
-  cours" list (each card badged Watch/Listen party) leaves their
-  sessions out, so classic and lounge parties never share a list.
-- **"Completed" gained a second trigger.** `PartyService
-  .completeCurrentItem` is now the one place an item counts as done. It
-  handles Emby Played, as before, plus static progress. It runs from
-  `advanceQueue`, and from a new host-only `"itemEnded"` socket event
-  for the *last* queued item. That item was previously never marked
-  Played at all, since there was no "next" to send for it.
-- **Missed = group-completed − watched in-app − Emby Played**, computed
-  by the pure `computeMissedIds`. Each viewer's own Emby `UserData` is
-  read from the source re-fetch under their own session.

-# Lounge party (watch party statique)
-
-## Les trois types de party
-
-| Nom dans l'interface | Quoi | Où |
-|---|---|---|
-| **Watch party** | party vidéo classique, éphémère | accueil, « Parties en cours » |
-| **Listen party** | party audio classique, éphémère (barre musique) | accueil, « Parties en cours » |
-| **Lounge party** | party statique : une série ou une playlist vidéo suivie sur plusieurs séances | onglet « Lounge parties » |
-
-Côté code, la lounge party reste nommée « static party » (`StaticPartyService`,
-route `/static`, `staticLink`...). Seuls les libellés visibles ont changé. Sur
-l'accueil, chaque carte affiche un badge « Watch party » ou « Listen party ».
-
-## Objectif
-
-Suivre une série entière, ou une playlist vidéo, en groupe sur plusieurs
-soirées. L'app mémorise :
-
-- **l'avancement du groupe** : les éléments terminés ensemble, et où la
-  dernière séance s'est arrêtée ;
-- **l'avancement de chaque personne** : ce qu'elle a vu.
-
-Une personne qui revient ou qui rejoint en cours de route voit la liste de
-ce qu'elle a **manqué** et peut le rattraper.
-
-Contrairement à une watch party classique, qui vit en mémoire et disparaît
-avec son dernier membre, une watch party statique est **persistée sur
-disque** et survit aux redémarrages.
-
-## Modèle
-
-| Entité | Où | Rôle |
-|---|---|---|
-| `StaticParty` | `server/src/types.ts`, persistée | la « saison » du groupe : items, progression du groupe, membres |
-| `StaticPartyMember` | dans `StaticParty.members` | `watchedItemIds` = ce que la personne a vu dans l'app |
-| Séance | une `Party` live ordinaire + `party.staticLink` | la lecture elle-même : lecteur, sync, flux partagé et lobby réutilisés tels quels |
-
-`party.staticLink.mode` :
-
-- `group` : la séance du groupe. Un item terminé fait avancer le groupe
-  **et** est crédité à chaque participant connecté.
-- `catchUp` : un rattrapage. L'item est crédité aux participants connectés
-  uniquement, le groupe ne bouge pas.
-
-`party.hiddenFromLobby` : un rattrapage en solo n'apparaît pas dans la liste
-des watch parties en cours.
-
-## Règles
-
-- **Item terminé** :
-  - l'hôte passe à l'item suivant (`next`),
-  - ou le dernier item de la file se termine (`itemEnded`, nouvel event socket réservé à l'hôte).
-
-  Les deux passent par `PartyService.completeCurrentItem`, qui gère aussi le
-  flag `Played` d'Emby. Un même item n'est jamais compté deux fois de suite
-  (`lastCompletedItemId`). C'est la même heuristique que
-  `PlaystateService.markPlayed` : « le groupe est passé à la suite » vaut
-  « vu ».
-- **Seuls les membres connectés** au moment où l'item se termine sont
-  crédités. Une personne partie en cours d'épisode l'a donc manqué ; elle
-  peut le marquer comme vu.
-- **Manqués d'une personne** : les items terminés par le groupe, dans
-  l'ordre de la liste, moins ceux qu'elle a vus dans l'app
-  (`watchedItemIds`), moins ceux qu'Emby a déjà en `Played` pour son compte
-  (vus ailleurs). C'est la fonction pure `computeMissedIds`.
-- **Reprise** : le sweep existant des 20 s enregistre la position de l'hôte
-  (`group.resumePositionTicks`). La séance suivante démarre avec cette
-  position comme position de l'hôte, que `Player.ts` utilise déjà pour
-  placer la première image.
-- **Nouveaux épisodes** : chaque lecture de la page, et chaque lancement de
-  séance, recharge la source. Les nouveaux items sont ajoutés à la fin ; les
-  items retirés de la source sont conservés dans l'historique
-  (`mergeItemLists`).
-- **Accès** : ouverte à tous les comptes Emby.
-  - Rejoindre = devenir membre. Rejoindre la séance du groupe depuis le
-    lobby rend aussi membre de la watch party statique.
-  - N'importe quel membre peut lancer la séance ; celui qui la lance en
-    devient l'hôte.
-  - Quitter efface sa propre progression.
-  - Seul le créateur peut supprimer la watch party.
-- **Contenus** : une série entière, **une seule saison**, ou une playlist
-  vidéo. Une playlist musicale est refusée.
-  - Série entière : tous les épisodes de toutes les saisons à partir de S1E1.
-    Les spéciaux (saison 0) sont exclus : Emby les trie en premier, et une
-    séance commencerait par eux (`CatalogService.seriesQueueFrom`). Les
-    lounge parties créées avant ce changement gardent leurs spéciaux déjà
-    en liste.
-  - Saison : uniquement les épisodes de cette saison
-    (`CatalogService.seasonQueue`, par `SeasonId`, sinon par numéro de
-    saison). La source garde `seriesId` et `seasonNumber`, car les
-    épisodes sont récupérés par série puis filtrés. Nom par défaut :
-    « Série - Saison », avec l'affiche de la série.
-
-## API (`server/src/index.ts`)
-
-| Méthode | Route | Rôle |
-|---|---|---|
-| GET | `/api/static-parties` | liste, avec le nombre de manqués de l'utilisateur et la séance en cours |
-| POST | `/api/static-parties` | `{sourceId, name?}` : série, saison, épisode (sa série) ou playlist |
-| GET | `/api/static-parties/:id` | détail : items + état groupe / utilisateur, membres, `missedItemIds` |
-| POST | `/:id/join`, `/:id/leave` | devenir membre / quitter |
-| DELETE | `/:id` | supprimer (créateur uniquement) |
-| POST | `/:id/session` | lancer la séance du groupe, ou rejoindre celle en cours, puis renvoyer `{partyId}` |
-| POST | `/:id/items/:itemId/watched` | marquer comme vu |
-| POST | `/:id/catch-up` | `{itemIds, mode: 'solo'\|'party'}`, renvoie `{partyId}` |
-
-## Persistance
-
-- `StaticPartyStore` écrit **un fichier JSON par watch party** :
-  `${DATA_DIR}/static-parties/<id>.json`, au format `{version: 1, party}`.
-  - `DATA_DIR` vaut `./data` par défaut, et `/data` dans l'image Docker.
-    `docker-compose.yml` y monte `./data`.
-  - Un fichier par party limite les dégâts : une écriture ne touche que la
-    party modifiée, et un fichier corrompu ne coûte que cette party-là.
-  - L'écriture est atomique (`.tmp` puis `rename`) et debouncée (2 s) party
-    par party. Elle est flushée de façon synchrone sur `SIGTERM`/`SIGINT`.
-  - Au démarrage, un `.tmp` restant (écriture interrompue) est supprimé ; le
-    vrai fichier, s'il existe, est la dernière version complète.
-  - Un fichier corrompu (ou dont le nom ne correspond pas à l'id) est
-    renommé en `.corrupt` et ignoré ; les autres parties se chargent
-    normalement. Le serveur ne crashe jamais pour ça.
-  - Supprimer une party supprime son fichier et annule toute sauvegarde en
-    attente pour elle.
-  - Migration : l'ancien fichier unique `${DATA_DIR}/static-parties.json` de
-    la première version est éclaté en un fichier par party au premier
-    démarrage, puis renommé en `.migrated` (conservé, pas supprimé).
-- Pas de SQLite : l'image tourne en Node 20 (pas de `node:sqlite`), une
-  dépendance native serait une première dans l'image, et les données sont
-  minuscules.
-- `livePartyId` n'est jamais persisté : un redémarrage termine toutes les
-  séances, et la reprise se fait depuis la position enregistrée.
-
-## Client
-
-- `views/staticParty/` (route `/static/:id`) contient :
-  - l'en-tête, avec la progression du groupe et le bouton lancer / rejoindre
-    la séance ;
-  - « Tu as manqué », avec pour chaque élément cases à cocher, *Regarder en
-    solo* et *Marquer comme vu*, plus deux actions groupées : rattraper en
-    solo, ou lancer une watch party de rattrapage ;
-  - les membres ;
-  - la liste complète des items.
-- Page série (`views/series`) :
-  - en-tête : « Lancer toute la série » (watch party) et « Créer une lounge
-    party » (série entière) ;
-  - au-dessus des épisodes de l'onglet de saison sélectionné : « Lancer
-    cette saison » (watch party) et « Lounge party de cette saison ».
-- « Créer une lounge party » sur `views/playlist` (vidéo uniquement).
-- Onglet dédié « Lounge parties » (sidebar et menu mobile), route
-  `/static` (`views/staticParties/`) : une carte par watch party avec la
-  progression, le prochain élément, un badge « N manqués » et une pastille
-  « séance en cours ». L'onglet reste actif sur la page d'une party.
-- Séparation avec les watch/listen parties classiques : la liste « Parties
-  en cours » de l'accueil exclut les séances de lounge party
-  (`staticPartyId` non nul) ; elles ne s'affichent que dans leur onglet.
-
-## Limites connues
-
-- « Vu » reste une heuristique : passer à la suite compte comme vu, comme
-  pour le flag `Played` d'Emby. Il n'y a pas de seuil de pourcentage.
-- La liste et le détail relisent la source Emby à chaque affichage (une
-  requête par watch party pour la liste). C'est acceptable à l'échelle d'un
-  serveur perso ; à mettre en cache si la liste grossit.
-- Plusieurs watch parties statiques peuvent exister sur la même série
-  (des groupes différents) : c'est voulu, sans déduplication.
