   TMB Product Archives (3.6.0)
   File: assets/css/tmb-archive.css — shop, product categories, tags, brands,
   product search. Loaded by inc/archive.php on those pages only.
   Product cards (.co-prod-*) and pagination keep their styles from
   tmb-universal-styling.css; this file adds the hero, sub-category chips,
   filter bar, related sections and empty state.
