/* ----- Scroll-reveal animations --------------------------------- */

     (scripting: enabled) AND (prefers-reduced-motion: no-preference)
   so no-JS visitors see content immediately (not trapped invisible),
   and motion-averse visitors skip the animation entirely. JS in
   static/js/animations.js adds .visible to each target as it scrolls
   into view; there's also a 3s safety-net fallback in the JS that
   force-reveals anything still hidden. */
