Corrections from testing feedback:
- Remove the greeting — the current QBZ discovery view has no greeting,
only the tab selector. Drops HomeState.greeting and the chrono dep.
- Quality badge is now the icon-only badge (hi-res.svg, or cd.svg in a
framed square), not a numeric text pill. AlbumCardItem carries a
quality tier instead of a quality string.
- Tighten the album card: deterministic 274px height, title and artist
in a 2px-spaced stack — removes the large gap between them.
- SectionRow no longer scrolls vertically (vertical-scrollbar-policy
always-off, height pinned to the card height).
- Artwork is downscaled to 264px on decode instead of holding ~600px
source textures.
