The full player previously sat dead-center on wide viewports — cover
+ controls capped at max-w-md left the right two-thirds of the screen
empty while the queue remained behind a drawer toggle. Split the
layout at lg+:
- Extract QueueList from QueueDrawer (header + count + scrollable
list body + empty state); the drawer now wraps QueueList for its
slide-in chrome, and the now-playing route embeds it directly.
- now-playing: at lg+ render the player as a left section + a 384px
(xl: 448px) aside with QueueList. Below lg the layout is unchanged
single-column and the drawer toggle in the bottom row still opens
it (lg:hidden on the toggle button keeps it out of the way once
the panel is permanent).
- QueueList owns the close X conditionally — drawer passes onClose
and the bind:closeButtonRef for focus management; embedded panel
omits both since it has no dismiss action.
QueueTrackRow's drag-to-reorder, click-to-jump, and current-row
highlight all carry over for free since they're owned by the row
component.
PlaylistCard: per-artist system variants (songs_like_artist) all share
one variant tag but exist as one playlist per seed artist; routing
their play handler through systemShuffle(variant) hit the wrong
playlist (or 404). Detect via seed_artist_id != null and fall through
to getPlaylist(playlist.id) for those; still tag the queue with the
variant so source attribution stays correct.
smoothPosition.svelte.ts: new useSmoothPosition() hook mirrors
Android's rememberSmoothPositionMs. player.position only updates
~4 Hz (HTML audio timeupdate), so the seek thumb stepped visibly;
$effect resets on each canonical tick / seek / track-change and a
rAF loop extrapolates at playback rate between ticks.
Wired into both PlayerBar.svelte (mini + expanded seek rows) and
now-playing/+page.svelte. Seek input handler still reads the raw
range value (not smoothed.value) so user drags stay authoritative.
Mirrors Android's NowPlayingScreen. New /now-playing route renders
outside the Shell (no top bar, no PlayerBar) so it's a focused full
viewport: large square cover, title + linked artist/album, full-width
scrubber with timestamps, prominent transport (prev / play-pause /
next, with a 56dp circular play button), shuffle + repeat toggles,
like button, volume slider, and a queue button that opens the
existing queue drawer.
Tapping the cover or title area in PlayerBar (compact + desktop)
now navigates to /now-playing instead of the album page. Pattern
matches Spotify / YouTube Music. The album link stays reachable via
the album-name link inside NowPlaying itself, so no nav is lost.
Back button in the NowPlaying header uses history.back() with a
fallback to /. Empty state when no track is loaded points the user
at Home or the Library.
