/* DEEPMINE UI v4 — shop page styles (工具 · data-mode="shop").
   Markup: management-panels.mjs renderShopPanel / renderMaterialChips; the quantity picker in
   #sheet-controls is generated by mobile.mjs (.quantity > span + button[data-qty].chosen).
   Card states come from article.shop-card[data-state=ready|short-dmt|short-materials|locked|max|buyout|field-full].
   Progressive unlocks add the 天赋树 card (article.unlock-card, same states) and the pre-market footer
   (.shop-market-tip.shop-tree-tip); the "新" ribbon (.is-new > .shop-new-ribbon) lives in ui/onboarding.css.
   Material chips (.materials-block/.material-list/.material-chip) live in ui/components.css; they are shared
   with the talents detail drawer. */
