   Category, auction and order pages.

   Every class name here is a contract with the inline Firestore modules in the
   category-*.html / auctions.html / orders.html pages — names must not change.
   What did change: the seven per-category colour blocks (~420 lines of copied
   rules) collapsed into a single `--cat-accent` custom property set per body
   class, and the light palette moved onto the AVIA design tokens.
