Badge text color was hard-coded to text-primary-foreground for every
tone, which renders as parchment light. Pairing light text with the
amber warning background (L=0.82) or the warm-silver muted background
(L=0.77) produced light-on-light collisions — the "9" on the active
Messages row and the "4" count on Work were nearly unreadable.
Route each tone through its own semantic foreground token:
danger -> bg-destructive text-destructive-foreground
warn -> bg-warning text-warning-foreground (dark text on amber)
default -> bg-muted text-muted-foreground
Also pull .dark --muted and --secondary off the --card lightness
(0.296 -> 0.360) so bg-muted is actually visible against the sidebar
card surface. This fixes not just the count pill but every hover/muted
fill across the app (toggle rest state, subtle button backgrounds, etc)
that previously vanished into the card.
Typecheck and build:verify clean.
