Smoke round 2 (owner feedback: content area was an opaque black slab, motion
imperceptible, ambient≈blurred).
- Content-area sweep: 27 content-view roots go transparent when the app
background is active (was opaque Theme.surface-main covering the background) —
Home/Discover/Album/Artist/Search-adjacent/Favorites/Playlist/LocalLibrary/
MyQBZ/managers/etc. Content well (AppShell) transparent too.
- SongCard (NPB classic), search input box, cortinilla panel go translucent so
they stop reading as opaque slabs over the background.
- ambient.wgsl: much faster + bigger blob travel + stronger domain warp +
brighter/more saturated so the flow is obviously moving and clearly distinct
from the blurred-art mode.
- Defaults: dim 0.35, surface-alpha 0.5.
Checkpoint during smoke iteration (owner-requested). Base: 76ea5a82.
