   V&D TECH — PREMIUM STYLESHEET
   Style direction: quiet luxury, editorial spacing, restrained motion.
   Palette is locked to the brief's tokens below — do not introduce new colors.
   NOTE: hero-redesign.css loads after this file and owns the fine-grained
   hero visuals (3D canvas, glass cards, magnetic buttons). The rules in this
   file provide a complete, non-broken baseline for every hero selector so the
   page still looks correct even if that file is absent, but hero-redesign.css
   is free to refine anything under .hero-section-new.
