/* ML Arch Studio - motion layer. Ported from the DV8 Motion Kit (Oct 2026), retuned for an
   interiors studio: slower, quieter, more like a door opening than a reveal.

   motion.js sets html.mo only when motion is allowed, and every scene variable defaults to
   its finished state, so reduced motion, a failed script or a crawler all get a complete,
   still page. Nothing above the fold is ever clipped or faded (LCP). */
