   Design: light, airy app-store look. Floating rounded header, soft cards
   (hairline border + faint diffused shadow), violet accent, per-category
   color tones, generous radii. No gradients, no transform hovers.
   Dark theme: tokens swap via [data-theme="dark"] on <html> (cookie-backed,
   set server-side to avoid FOUC — CSP forbids inline scripts) with a
   prefers-color-scheme fallback when no explicit choice was made.
