   --------------------------------------------------------------------------
   用于三处：Public 商城（public/base.html）、客户购物车/订单（client/base.html）、
   商城后台（staff/base.html）。三端各有一套主题变量，因此本文件**不依赖**任何
   一端的变量，只使用自己的 `--mall-*`，避免在 ds.css / public.css 之间来回污染。
   视觉延续 P8-B「幕一国際物流」蓝白调性（navy / royal / blue），不重设计品牌。
   移动端纪律：所有网格用 minmax + 1 列回落，任何卡片禁止撑出横向滚动条。
