 * Hero: a load sequence (tu-rise), a slowly drifting contour map and a gently floating phone.
 * Page: sections and cards rise in as they scroll into view (tu-reveal, added by the script in
 * layouts.landing, which also sets html.tu-js — without JS nothing is hidden). Cards and
 * screenshots respond to hover. Everything is off for people who prefer reduced motion. */
