bg-brand-mint (#A6DAD8) on text-brand-navy (#012851) = 3.5:1, fails AA
for text-xs (12px). bg-white (#fff) on text-brand-navy = 14:1 AAA.
White also reads as a distinct shape against the navy header background.

- Normalize all header icon buttons to white/65 + white/10 hover bg
- Fix guest person icon (img tag needs brightness-0 invert, not text color)
- Add missing focus-visible rings to ThemeToggle and LanguageSwitcher
- Use focus-visible:rounded on nav links so active underline stays sharp
- Bump burger/nav breakpoint from sm→lg to prevent overflow on tablets

In dark mode --c-primary switches from navy (#012851) to mint (#a1dcd8).
Buttons using bg-primary+text-white showed white text on mint at 1.4:1
contrast — invisible. bg-brand-navy buttons were also invisible (navy on
near-black canvas, 1.3:1).
Replaced in 28 components app-wide:
- bg-primary ... text-white → text-primary-fg
- hover:bg-primary hover:text-white → hover:text-primary-fg
- bg-brand-navy ... text-white + hover:bg-brand-navy/90 →
bg-primary ... text-primary-fg + hover:bg-primary/90
Light mode is unchanged: primary-fg = white in light mode.
Dark mode: primary-fg = navy (#012851) on mint bg = readable.
