   pages/platform.css - the reliability page. Only what this page alone needs; everything else is v1's vocabulary in components.css.
   Every demo is a v1 console (glass panel, title bar, "Live demo" pill) with v1's architecture-diagram language inside it: rounded
   --bg-3 boxes, blue dashed flow for calls, gold for configuration, green for health, red for a part that is down.
   A part that is down is never color-only: it is hatched, says "Down", and its button reports aria-pressed.
