   Shared design system for the Foosball site - "Tournament
   Orange" dark theme, translated from the Stitch mockup's
   DESIGN.md into plain CSS custom properties (no Tailwind, no
   Google Fonts/icon-font CDN - system fonts + inline SVG icons
   only, keeping the site fully self-contained).

   Link this from a page instead of embedding a duplicate <style>
