/* ══════════════════════════════════════════════════════════════════════
   Landing page — clean redesign

   Design principles:
   - Generous whitespace between sections (100-120px vertical)
   - Max-width constraints for readability
   - Uses project CSS variables from base.css exclusively
   - No --surface (undefined) — use --bg-card, --bg-surface, --bg-input
   - Apple-style: subtle borders, soft hovers, restrained color
