   the scroll reveal, the carousel's slide, and the hero's pulsing dot. Hover
   and focus transitions stay — those are responses to a deliberate action.

   This block must stay LAST. A media query carries no extra specificity, so an
   ordinary rule further down the file (`.carousel-track`) would otherwise win. */
