/* ============================================================================
 * pick.bosbm.ai —— 選品沙盒工作台樣式（疊在 /theme.css + /backend/backend.css 之上）
 * ----------------------------------------------------------------------------
 * 沙盒＝草稿態工作台：帶頭人自己的後台，可見成本 RMB / 毛利 / 藏價拆解（調價用）。
 * 只補沙盒專屬元件：頂欄、工具列、草稿商品卡（勾選 + 成本 badge）、編輯側欄抽屜。
 * 骨架（container/btn/input/select/panel/slider-row/calc-*）沿用 theme.css + backend.css。
 * ⚠️ 藏價分界：此為「操作者後台」，成本可見；go.bosbm.ai 公開前台永遠只出 sale_price_twd。
