/* ============================================================
   refine-shop.css — Ztor 2.0 SHOP family rework
   Mobbin-benchmarked storefront + auction patterns on the Ztor skin.
   References: Weverse (fan-store status tags + wishlist), Faire/Cosmos
   (hover quick-add, price-forward grid), Rarible/Foundation (timed-auction
   card: countdown + current bid + bid count + outbid state).

   SCOPE: every rule sits under `body.rf-shop`. Never touches tokens.css
   or components.css. Linked AFTER components.css on the 5 shop pages.
   Motion: transform/opacity only; honored prefers-reduced-motion at end.
