   h5/assets/styles/tokens.css —— 设计令牌与通用组件
   --------------------------------------------------------------------------
   与小程序 styles/tokens.wxss + theme-user.wxss 一一对应。
   唯一的换算：小程序用 rpx（750 设计稿），H5 用 px（375 设计稿），**数值折半**。
   例：28rpx → 14px，88rpx → 44px，32rpx → 16px。

   主题机制也一致：
     · 这里给出的是一套「白底黑字」的默认值（等价 theme-user.wxss）
     · 商户主题色由 core.js 的 applyTheme() 以 CSS 变量覆盖 :root
     · 主题色只作为**强调色**（按钮 / 价格 / 选中态），不翻转底色
