/* ==========================================================================
   base.css — design system and site shell
   --------------------------------------------------------------------------
   Loaded on every page, before motion.css, panel.css and the page CSS.
   Contains: design tokens, reset, typography, layout helpers, buttons,
   links, header, footer and the shared product card.

   Owner, safe to edit:
   - Colours, font, spacing and timing in the :root block below.
     (Everything else on the site reads these values, so change them here.)
   - Header height (--header-h) and page side padding (--gutter).
   Hover effects exist only on .btn, .cart-toggle and the quick add on
   product cards (by design).
