   GARAGE-ONLINE — SHOP COMPONENTS
   Fase 2 · Webshop
   --------------------------------------------------------------------------
   Shared, reusable shop chrome + page components. Builds ON TOP of
   brand.css design tokens (:root custom properties) — never hardcode a
   value you can read from a var(). Reused across all shop pages
   (categorie, product + future home pages) so chrome stays identical.

   Contents:
     1.  Shop nav / header (+ mobile menu, cart badge)
     2.  Breadcrumb
     3.  Page heading helpers
     4.  Category page layout (sidebar + content)
     5.  Filter facets
     6.  Sort toolbar + grid/list toggle
     7.  Product grid (cards fill cells) + list view
     8.  Pagination
     9.  Product detail (PDP) layout
     10. Gallery (main + thumbs)
     11. Buy box (price, stock, stepper, USP)
     12. Rating stars
     13. Specs table + description
     14. USP / trust strips
     15. Shop footer (multi-column)
     16. Utility helpers
     17. Responsive (900px / 560px)
