/* ===================================================================
   LuminaEducation.tech — styles.css

   Refactor changelog (this version):
   1. Z-index system: hardcoded values replaced with --z-* variables
   2. Dark mode: consolidated via variable reassignment under html.dark
      (component-specific overrides retained only where values diverge
      from the variable system — gradients, navbar translucent surface,
      footer deepest black, marquee tinted background)
   3. Marquee: padding-right balances the gap for seamless loop math,
      translate3d in keyframes, hover-pause, will-change removed,
      manual scroll enabled under reduced-motion
   4. Float cards: !important removed from animations so reduced-motion
      can cleanly override
   5. Reduced-motion block: cleaner organization, explicit suppression
      for slowSpin/glowPulse/portraitBreathe, manual scroll fallback
   6. Box-sizing reset extended to pseudo-elements
