/* CLARA - shared styles across landing + app
   Design system notes:
   - Neutral scale: Tailwind zinc, used for structure/text.
   - Single brand accent: indigo ("accent" in tailwind.config, renderer.tsx) —
     reserved for links, focus states, and "AI / smart feature" affordances,
     so it reads as a distinct signal from the near-black primary action color.
   - Semantic status colors (success/warning/danger/info) are applied via
     Tailwind utility classes per-component (green/amber/red/blue), but should
     always pair a light background with a matching border for definition —
     see .badge and .banner-* below.
