   "Casbah Azure" system. Tokens flip on html[data-theme]. Never pure black/white.
   No pills, no glassmorphism/backdrop-blur, no accent side-stripe borders,
   no gradient text. Motion is transform/opacity only and reduced-motion gated.
   Fully responsive: fluid type/space via clamp(), square countdown cells via
   flex + aspect-ratio (never overflow), capped sections for ultra-wide.
