Un-gates music libraries; adds CardShape.square plumbing (circular
artists), artists/albums/tracks browse groupings with per-grouping
sorts, audio playlists tab, artist + album detail screens with dpad
track rows, music context-menu actions, and a stub MusicPlaybackService
seam for the upcoming engine.
Extract the manage/reorder-libraries sheet from the libraries screen into
a shared widget with a public launcher, and add a settings tile (top
group, gated on having libraries) that opens it. The libraries screen
keeps its side-nav refresh and re-select-on-hide behavior via launcher
hooks; the TV dialog path lives in the launcher so the entry works there
too.
Desktop overlay sheets defaulted to a fixed 400px max height, which left
the reorder sheet ~280px tall. Both default-constraint sites now use 75%
of window height, matching mobile.

Profile traces showed 100-370ms UI-thread frames while scrolling the
library screen, dominated by rebuilding and inflating media cards.
- Gate per-card focus/pointer chrome on input mode: FocusableWrapper
skips the scale/border wrappers and creates its AnimationController
lazily outside keyboard mode, and ClickableCursor plus the card tap
region only build MouseRegion/InkWell machinery on desktop - TV and
touch use a bare GestureDetector. Hub cards also drop their outer
gesture wrapper outside keyboard mode; the card's own tap region
always won the gesture arena anyway.
- Memoize sliver children (SliverChildMemo): browse/collections grids
and hub rows return identical widget instances for unchanged items,
so delegate swaps from pagination, watch-state, and deletion
setStates no longer rebuild every realized card inside layout. The
browse tab prunes the memo in lockstep with focus-node eviction so a
cached card can never resurrect a disposed FocusNode.
- Budget fresh inflation (CardInflationBudget): while a scrollable is
moving in pointer/touch mode at most one new card inflates per frame,
the rest render as SkeletonMediaCard and upgrade on following frames.
Hub rows also stop pre-inflating 250px of off-screen cards on entry.
Device traces: worst frame 373ms -> 103ms, per-card build 3.6ms ->
2.4ms median; remaining row-entry work is spread across frames.
Skia's dithered gradient shaders cost ~10ms per full-screen pass on
Mali-class TV GPUs: the two spotlight scrims alone were ~20ms of a 27ms
raster frame, while flat blended quads at the same coverage are ~free.
Bake axis-aligned LinearGradients once into cached 1x1024 premultiplied
strip textures drawn as stretched quads (shader fallback for unsupported
shapes and the first frame). Converted the spotlight, TV detail backdrop,
app-bar scrims, rail bleed, person-card overlay, and the video-controls
scrim, which now also keeps one widget type across hasFrame flips so the
controls subtree survives in-place source switches.
Scripted-browse on a Mali-G31 box: draw p50 27.5ms -> 7.1ms, swap block
20.3ms -> 0.9ms, janky draws 69% -> 2%; screenshots pixel-identical.
* fix(plex): show PGS subtitles when transcoding
Bitmap subtitles (PGS/VOBSUB) disappeared from the menu while transcoding on Plex, leaving only "Off". The MKV transcode already supports them, so embed them in the stream like text subs. Now they show up and can be turned on.
* fix(plex): give bitmap subtitle codecs the right sidecar extension
getSubtitleExtension fell back to .srt for vobsub, pgssub and dvb subs. Map them to .sub/.sup so it stays consistent with isImageSubtitleCodec and any sidecar URL or download uses the correct extension.
The keyboard is a navigator route, so a screen swapping out its form
left it floating over the new content. showTvVirtualKeyboard now
returns a route handle and the field host closes it on dispose.
The TV keyboard dialog froze the field's callbacks at open time, so the
search screen's done key fell through to unfocus() once results arrived.
Resolve callbacks against the latest field widget at invoke time, and
give the search screen a TV submit handler that focuses the first result
or flushes the pending debounce.
Adds nullable canPop + onSystemBack to OverlaySheetHost. When canPop is
set, the host installs its own PopScope that closes an open sheet on a
system/route back instead of popping the screen; null keeps today's
behavior. Lets screens drop their hand-rolled sheet-back PopScopes.
