   设计定调（Design Direction）：
   受众  全球外贸买家（非洲 / 欧美），手机端看货 → 询盘 → 下单
   方向  国际外贸电商——纯白底 + 橙红主色，信息密度优先；
         商品卡直接挂「发询盘」按钮，买家最常做的动作不用进详情就能点；
         公告降为一条细线，黄金位置全部让给商品。
   记忆点 ①橙色询盘按钮   ②方形商品图 + 大字橙红价格
         ③细条公告不占位   ④国际化无衬线，弃用衬线文艺腔
   字体  Plus Jakarta Sans（拉丁） / PingFang SC + 微软雅黑（中文）
   色板  主橙 #FF6A00 · 深橙 #E85D04 · 浅橙底 #FFF4EA · 极浅 #FFF9F5
         价格 #FF3D00 · 文字 #1F1F1F / #6B6B6B / #9E9E9E
         边框 #EBEBEB · 页面底 #F7F7F7
   兼容  360 / IE11：色值全部硬编码，不使用 CSS 变量；字体本地自托管
