/* MOTION_R01 · OPTIC_SHOP_PREMIUM_MOTION_AND_INTERACTIVE_EXPERIENCE_R01
   Jedan sistem pokreta za ceo sajt. Pravila:
   - samo transform, opacity, clip-path i mask (bez animiranja layout svojstava);
   - pokret vezan za skrol ide kroz CSS scroll-driven animacije (animation-timeline), bez scroll slušaoca i bez otmice skrola;
   - bez podrške ili uz prefers-reduced-motion: sajt izgleda tačno kao pre ove runde (sve je završno stanje);
   - zaključana sekcija HOME_VISIT (.r5-visit) se ne dira.
