   SPROAT SYSTEMS MOTION LAYER
   Scroll reveals, micro-interactions, and ambient animation.
   Loaded after style.css. Everything here is progressive
   enhancement:
   - Reveal-hidden states only apply under html.js, so content
     is fully visible without JavaScript.
   - prefers-reduced-motion collapses all of it (tokens.css
     zeroes durations globally; the .no-motion class set by
     motion.js prevents hidden states entirely).
