/* ============================================================
   Components. Every class here is a reusable UI primitive shared
   across pages (Atrium standard: glass surfaces, compact pill
   buttons, metric chips, equal stat tiles). Page-specific
   structural rules live in layout.css and the per-page sheets.

   Glass note: a backdrop-filter is only worth its GPU cost where
   real content scrolls underneath (sidebar, topbar, menus, modals,
   toasts). Cards sit over the static ambient gradient, where a blur
   is visually identical to none - so cards get the glass *look*
   (translucent tint, edge highlight, soft depth) without the filter.
