   ────────────────────────────────────────────────────────────────────
   Import THIS one file and you get the whole system:
     <link rel="stylesheet" href="/styles.css">
   It pulls in tokens → type → components, then layers base resets,
   accessibility defaults, and a small layout utility set.
   No build step. Works on static HTML (kvcn.org, learn.kvcn.org) and in
   the Pulse React/Vite app alike.
