/* Mobaide marketing site — "modern pixel", dark first.
 *
 * Deliberately NOT sharing central_server/static/style.css: that is the
 * light Bootstrap-flavoured dashboard sheet (--primary: #0d6efd) and none of
 * its tokens apply here.
 *
 * Two rules this sheet exists to enforce:
 *   - #6008AC and #6650A4 are FILL AND BORDER COLOURS ONLY. #6650A4 on #1E1E1E
 *     is ~2.6:1 and fails WCAG AA, so text on dark uses --accent / --text /
 *     --text-muted, never the brand purples.
 *   - No border-radius. The pixel look comes from square corners, stepped
 *     box-shadow frames, and 4px clip-path corner notches.
