/* ==========================================================
   product-detail.css
   Companion to product.css. Reuses .page-hero, .page-breadcrumb,
   .mono, .product-grid, .product-card, .product-view-btn,
   .media-grade, .doc-link, .catalogue-empty and .filter-reset
   as-is from product.css — nothing here redefines them.

   Colour / type tokens fall back to sane defaults via var(--x, fallback)
   so this file inherits home.css's real palette automatically if the
   variable names already match; otherwise it still renders correctly
   on its own.
