/* --------------------------------------------------------------------------
   MC Product Catalog
   Searchable, filterable product grid over the `products` collection.

   Scoped to .widget-mc-product-catalog. Reuses Arch primitives
   (.widget-grid, .widget-card, .form-*, .widget-button) and the Multichem
   editorial primitives (.mc-section-marker, .mc-hairline, .w-*). Nothing
   here is needed outside this widget.
