/* === Reduced motion ===
   Honour the OS-level "minimise motion" preference. `js/motion.js` handles the half CSS
   cannot reach — the particle, brand-wordmark and three.js animation loops, plus the
   typewriter. This block neutralises everything CSS owns (eleven keyframe sets, every
   transition, smooth scrolling) in one place instead of bolting a reduced-motion variant
   onto each rule.

   Durations collapse to 0.01ms rather than 0 so that transitionend / animationend still
   fire: a script waiting on one would otherwise hang forever. `animation-fill-mode:
   forwards` keeps elements that animate in from `opacity: 0` at their end state, so
   nothing is left invisible. */
