/* LIID Digital — demo build (new.liiddigital.co.za)
   FOURTH PASS. History, so the reasoning isn't lost:
   - Pass 1-2: scroll-triggered TEXT reveals only (opacity/translateY) —
     Ryan's feedback: that isn't "motion" to him at all.
   - Pass 3: added a full-bleed autoplay background video (dark register,
     liquid-glass nav/buttons sourced byte-for-byte from mindloop-hero.md
     in the motionsites.ai library) — closer, but still wrong: the video
     played on its own timer/scroll-fade, not truly scroll-SCRUBBED, and
     it was competing with the actual signature moment (Signal Path) for
     attention — Stage 5/9's own "one genuine signature moment" rule.
   - Pass 4 (this one): video approach scrapped entirely per Ryan's
     explicit correction. Hero reverted to calm/restrained/text-only.
     All real motion now lives in Signal Path, built as a true
     scroll-scrubbed illustrated timeline (GSAP ScrollTrigger,
     scrub:true + pin:true) — scroll position IS the timeline position,
     zero autoplay/timers anywhere. See js/script.js.

   Liquid-glass CSS (still used on nav/buttons) is copied byte-for-byte
   from the real sourced mindloop-hero.md spec. Fade-rise keyframes/
   timing (0.8s ease-out, 0/0.2s/0.4s delays) are the real sourced
   values too. LIID's own real gold accent is kept (validated across
   three passes now) on top of the sourced dark/glass mechanic. */
