Electron E2E on Windows measured the hovered play icon at 2.5:1 against
its fill (`player-theme.e2e.ts`, white-backing rasterization). White on
the #4f8eff accent is only 3.2:1 in theory, and the hover scale(1.04)
resampled the glyph, so a 1x display's antialiasing pushed it under 3:1.
- Fills under a white glyph (play, active tune) use a deeper
--pc-accent-blue-strong #3474e8 (4.4:1); hover darkens to #2a66d6
(5.3:1). The track fill and glow keep the #4f8eff accent.
- The play button no longer scales on hover.
