/* ════════════════════════════════════════════════════════════════════
   RADIANT OPTIMIZER — PREMIUM FX LAYER
   High-end motion, depth & micro-interactions layered on top of the
   existing "Precision Luxury" design.

   • Palette-locked: only uses the existing --black / --white / --blue tokens.
   • Loads AFTER the inline <style>, so later rules win where intended.
   • Fully respects prefers-reduced-motion.
   • Touch devices get lighter / no motion automatically (JS gated).
