   Guardian Command — design-system COMPONENTS layer.

   ▶ THE SAFETY CONTRACT:

      Every selector in this file MUST start with `.gc-`. No bare
      element selectors (input, button, table, a, *, etc.). No
      overrides of existing class names (.modal, .stat-card, .btn,
      .nav-item, .content-body, etc.). Allowed at-rules: @media,
      @keyframes (in gc-tokens.css), @font-face.

      Enforced by scripts/check-gc-namespace.js on every npm test.

   ▶ Adoption pattern:

      Views opt in by adding a .gc-* class to a specific element.
      Existing markup is untouched. Removing the .gc-* class falls
      back to default browser styling — no regression.

   ▶ Loaded AFTER gc-tokens.css in index.html.
