   Conventions
   - No !important. Breakpoints: 480 / 768 / 1024 / 1280 (min-width).
   - Component colours read scoped custom properties (--muted, --ice, --heading,
     --card-bg, ...) so the light ".section--relief" variant re-tokens them
     once instead of overriding every component.

   Hidden state only applies under html.js. The inline head script adds that class;
   if site.js then fails to load, its onerror handler (partials/page.html) removes the
   class again, so content is never left hidden. Uses the `translate` property so it never fights
   the transform-based hover lift on cards.
