/* ============================================================================
   ui.css — the shared design system for the portal and every app.
   Modern, readable layout with retro-arcade accents.

   Rules of thumb:
     * The pixel font (Press Start 2P) is for TITLES and BIG DISPLAY NUMBERS
       only. Never for body text, labels, inputs, or table data — it's a
       display face and it hurts to read at small sizes.
     * Colours come from the tokens below. Don't hardcode hex in an app.
     * Every app gets: <link rel="stylesheet" href="/lib/ui.css">
