/* Project theme — hand-coded CSS. No build step; plain CSS.
   Loaded after the design-system foundation + active project layer
   (see app/src/PageController.php → Requirements::themedCSS('theme')).

   Use the design-system token vocabulary so hand-coded UI stays consistent
   with the blocks: var(--color-*), var(--space-*), var(--text-*), etc.
   (the full list is in design-system/base/css/tokens.css).

   Example:
   .site-banner {
       background: var(--color-action);
       color: var(--color-on-action);
       padding: var(--space-6);
   }
