/* ═══════════════════════════════════════════════════════════════
   BaseFrame → UIkit Adapter
   Clean corporate design. ZERO border-radius, slate tones, precise
   spacing, bottom-border active nav. Like getuikit.com — editorial
   precision, alternating section backgrounds, sharp corners.
   All colors are explicit hex — no CSS variables that break in dark mode.
