Re-point neutral page surfaces, play-chip, and default popover from constant brand tokens to theme-aware aliases defined twice in deepdrft-tokens.css. Decorative navy/green sections and bespoke dark-glass panels untouched. Appbar-navy symptom deferred (palette C#, out of CSS scope).
Lift the WaveformVisualizer + control popover out of the 120px NowPlayingCard box into NowPlaying as a full-panel background layer; migrate the hero-right wrapper and its scoped styles from Home into NowPlaying.
Migrate hero, section-header, and section-split to MudGrid with xs/sm/md breakpoints (Spacing=0 to keep color panels flush); add @media collapse rules for genre/features card grids and the CTA banner. Visual styling unchanged at desktop width.
