/* Qrew website.
   Layout concept: a control room at night. A full-screen video stage stays fixed behind the page;
   content panels rise over it like cards being dealt, alternating "night" (always dark) and
   "day" (follows the viewer's theme). Colours and type follow the Qrew brand book
   (docs/design/agency-2026-09 in the app repo): logo orange, Inter for people, JetBrains Mono for machines. */
