   CMUI-Nav — Adaptive Morphing Navigation

   Navigation links are NEVER hidden behind hamburger menus. Instead,
   on narrow viewports they migrate to a floating glass dock at the
   bottom of the screen — where thumbs naturally rest (Fitts's Law).

   Layout morphing:
     Desktop  (>768px)  → Horizontal top bar with pill-hover links
     Mobile   (≤768px)  → Minimal top bar + floating glass bottom dock
     Compact  (≤359px)  → Tighter dock pills, condensed brand
     Landscape (short)  → Slim dock with reduced chrome
     Watch    (≤200px)  → Micro pill dock
