/* ==========================================================================
   STICK SURVIVORS: GUT GENUG — SHOP (every boss, after the arena reroll)
   Single-owner stylesheet for src/systems/credits_and_shop.js.
   Reuses the existing .cyber-rarity--* accent classes (common/rare/epic/
   unique/exceptional) already defined in ui_overhaul.css / final_0943's
   injected CSS, so shop cards match the same rarity language as the rest
   of the game.
