   6. SHARED PRODUCT CARD
   Moved here during the Phase 5 audit — this was previously only
   in home.css, which loads on the front page only. The Shop archive
   and single-product "Related products" section both render this
   same card via content-product.php but only load woocommerce.css
   (never home.css), so those cards were rendering with none of their
   base layout — no grid, no borders, no image sizing. Living here in
   the always-loaded stylesheet, every context that renders a product
   card gets consistent styling regardless of which page loaded it.

/* Category accent classes — power the color-coding on category cards
   AND product cards. Also moved here in the Phase 5 audit for the same
   reason as the product card rules above: these were home.css-only,

   the Phase 3 brief) was silently not working on that page at all. */
