   MockCall — shared design system
   A single stylesheet shared by the coach portal, admin portal, score page and
   login screens. Plain CSS (no build step). Design language adapted from the
   gemini_mockcall prototype: indigo + slate, large radii, soft shadows,
   Inter / Space Grotesk / JetBrains Mono.
   Many class names (.grade, .pill, .empty, .badge, .dim*, .idea*, .spark,
   .bar-*, .chart-*, .gauge-*) are kept so existing page JS keeps working.
