/* ==========================================================================
   PROSERMAT — Premium Product Card 2026
   --------------------------------------------------------------------------
   FASE 2 · Anatomía premium para las tarjetas de producto (.prod-card /
   .product-card). Se monta SOBRE la capa base (premium-storefront.css) y
   añade:
     • Border-radius 16px + box-shadow multi-capa
     • Hover spring (translateY + shadow brand)
     • Zoom suave de imagen al hover
     • Badges chip, wishlist flotante
     • Tipografía calibrada: brand uppercase, nombre lg, precio 2xl tabular
     • Tags por categoría con color semántico (sección 17)
     • Skeleton loader (.is-loading)

   Las clases legacy `.prod-card` mantienen los hooks JS existentes
   (wishlist injector, modal opener, filter chips, etc.) sin tocar app.js.
   Las clases nuevas `.product-card` son alias soportados para futuras vistas.
