   NVIL Motion — interactive web motion systems (EXP-004)
   A motion lab: ten scroll-driven sequences on one page. Everything under
   .mo is NVIL: near-black, thin lines, mono labels, the red mark. The
   engine writes progress into --p and a few data attributes; the CSS turns
   those into transforms, opacity and clip-paths. Nothing else animates.
