 *   --df-bg-darker: #0d0d0d  hero gradient bottom stop, footer
 *   --df-red:       #FF3939  primary accent, CTAs

 *   --df-ocean: #519670  success / `tip` admonition
 *   --df-amber: #FFB612  warning admonition
 *
 * Homepage-only rules live in stylesheets/home.css and are loaded

 *
 * Dark mode is intentionally disabled in mkdocs.yml — many migrated SVGs
 * and screenshots assume a light background.
