Three Slint-parity pieces that share the chrome surface:
- macOS menu-bar tray (NSStatusItem, tray_macos.rs) ported from the
reference — the K2 'macOS is a new implementation' ruling read the
reference backwards (it avoids muda entirely), and its absence made
close-to-tray quit the app on the Mac. Plus the custom-chrome window
mode (macos_chrome.rs): Qt 6.9 ExpandedClientAreaHint /
NoTitleBarBackgroundHint instead of fighting QCocoaWindow's style-mask
recompute, traffic-light centring, and the SafeArea inset in HeaderBar.
- Appearance rows that rendered, persisted and drove nothing now push
live: hide/show title bar, window-controls cluster side, track in the
window title, invert swipe navigation, auto-theme source selection
(wallpaper/image/system) with regeneration on source change.
- use_system_title_bar now defaults per-OS (custom chrome on macOS),
matching the reference — the hard-coded 'true' also leaked into the
Slint build through the shared ui_prefs.json.

**Deferred external rows.** The album page awaited the Last.fm row before
publishing anything, so the tracklist waited on an external service plus
MusicBrainz. It publishes in stages now — header and tracks first, then each
Qobuz rail as it lands, then Last.fm — with every patch merged under a
generation counter so a late reply for album A cannot paint onto album B. The
artist page was already staged this way; its views were the part still showing
bare "Loading…" text.
**Skeletons as the standard.** One control, new variants rather than new
components, mounted across the views. Its second job is the one the owner
named: cleanup. A cover that never resolves settles the placeholder once and
reveals the card's own empty state instead of shimmering forever — local albums
with no embedded art produce no artwork entry at all, so a placeholder gated
only on "not arrived yet" would never stop.
**Local artwork streams.** Fifteen seconds to first cover on a 1274-album grid
was one batch emitted after the whole window resolved. Each cover emits as it
resolves now, visible band before prefetch margin.
**Lyrics migrated.** Smooth sync instead of a 1 Hz tick, word-level karaoke
where the document carries it, the surrounding-line dimming, the controls
flyout and the translation layer the v10 backend already supported. Exactly one
row subscribes to the 30 Hz output; the timer drops to 250ms when paused or
hidden.
**Navigation by mouse and touchpad.** Side buttons and a two-finger horizontal
swipe, matching #653 — including the part that matters, which is that a swipe
over a carousel scrolls the carousel. The layer is declared first in the shell
so everything else gets first refusal.
**Context menus.** Brought to the Slint inventory, Play later included, with
right-click opening the same menu as the button everywhere. Entries whose seam
does not exist are hidden rather than shipped inert.
Two controls that rendered and no-opped are now honestly disabled: the My QBZ
nav row, which routes to a view the shell has no case for, and three sidebar
menu entries with no backing call.
The sidebar caret was never a condition bug. The row is a positioner and the
name cell's width ignored the count label, so a folder WITH content pushed the
chevron past the clip — which is why it vanished exactly when it mattered.
