/* ---- Reduced motion ----
   One site-wide answer for anyone who has asked their system for less movement.
   Two details this project got wrong before:
   - `*` does NOT match pseudo-elements, so a pulsing `::before` dot kept
     animating right through a rule that looked like it covered everything.
   - Suppressing an entrance animation must never leave content behind. Every
     animation here is decorative or animates *into* a state the element already
     has statically, so removing it reveals rather than hides. Anything added
     later that starts at opacity:0 must reset itself in this block.
   scripts/check-reduced-motion.mjs loads every page in both settings and fails
   if something still moves — or if anything ends up invisible. */
