   ASHEN THRONE - SHOP page (shop.html)
   Loaded AFTER theme.css + mint.css + hub.css. Owns the game-shop
   shell: the left category rail, the Golden Ashes custom-amount
   storefront (buy-hero + chest grid), and the Token placeholder.
   The Mint tab reuses the mint-station chrome from mint.css.
   Tokens/fonts come from theme.css - no redeclaration here.
