/* ==========================================================================
   前台移动端 H5（app/index）样式
   --------------------------------------------------------------------------
   与代理中心移动端（m_assets/m.css）刻意分开的原因：
     两者受众不同 —— 这里是**终端客户**下单页，需要更强的引导性与信任感；
     m.css 是**代理工作台**，偏工具化的冷灰克制风。
     共用一套变量只会让两边都别扭，所以各自成文件，但**设计令牌保持同源**
     （灰阶、圆角、边框宽度、字体栈），保证视觉上还是一家产品。
