/* ============================================================
   BHOGI STOREFRONT DESIGN SYSTEM
   Site-wide elevation, rhythm, and interaction layer, shared by
   Home, Category, and Product pages.

   Every color here resolves through the active theme.json
   (--bhogi-*/--cmp-*, injected by ThemeService) or app.css's
   structural tokens. Nothing is hardcoded to one business's
   palette — a seller can pick any of the 35 themes and this file
   renders correctly in all of them, light or dark.

   Load order: app.css (structural tokens) -> this file (shared
   primitives) -> header-elements.css / storefront-refinements.css /
   home-controls.css / home-media.css (page-specific refinements,
   which may still win on specificity where they intentionally
   override sizing for a particular surface).
   ============================================================ */

    /* Palette alias layer — same semantics as home-controls.css's
       --home-* tokens, but resolvable on every page, not only
       inside .home-page. Keep both layers pointed at the same
       theme variables so Home, Category, and PDP never drift. */
