/* ============================================================
   components.css — styles for the site's custom elements.

   Loaded after style.css and deliberately NOT wrapped in @layer:
   style.css is unlayered too, so keeping both in the same origin
   means ordinary specificity decides, and a component rule does
   not silently lose to an unrelated page rule.

   Every colour here comes from the tokens in style.css, so light
   and dark themes are inherited rather than re-declared.
