/* ==========================================================================
   HENGNUO CHUANGDA — English Edition Stylesheet
   配色与组件规范 100% 对齐中文站 whhncd.css：
   直接复用中文站同一套 --hncd-* 设计令牌（品牌色 / 深底 / 文字层级 /
   中性面 / 圆角 / 阴影 / 容器），仅新增英文站专属组件（region-pill、
   ship-bar、cn-callout）且全部派生自同一套令牌，不引入任何新色值。
   改进点：统一设计令牌、规范组件样式、补齐移动端抽屉导航与响应式断点。
