   Vision Lab Studio — one stylesheet, no framework.

   Motion follows Emil Kowalski's rules (github.com/emilkowalski/skills):
   transform, opacity and clip only; strong ease-out for entrances; springs
   for anything that follows the pointer; reveals fire once; hover only for
   real pointers; reduced motion keeps the fades and drops the movement.
