   ANIMATION UTILITIES
   -------------------------------------------------------------------------
   "Luxury through restraint": short, deliberate reveals, no perpetual
   motion. Every rule here is opt-in via a data attribute so components
   stay declarative. No-JS visitors see full, static content — the hidden
   starting state only applies once .js-enabled is present (see the inline
   script in <head>), and prefers-reduced-motion collapses everything to
   an instant, non-animated state (see tokens.css durations + the query
   below).
