/* ==========================================================================
   PremiumWeblap — "Ultramarin" design system
   Concept: a studio poster that reads twice — once for people, once for
   machines. Bone-paper chapters alternate with ultramarine chapters; a
   monospace layer carries the real machine metadata of the page.
   Notes: Mobile-first, GPU-friendly, prefers-reduced-motion aware.
