/* ============================================================
   ContentFlow H5 外壳样式
   ------------------------------------------------------------
   这里只放「浏览器环境需要、小程序里不存在」的东西：

     1. 外壳布局：导航栏 / 页面容器 / 底部 tabBar
        （小程序的导航栏和 tabBar 由微信客户端提供，网页里得自己搭）
     2. 弹层定位：小程序里 fixed 的弹层改成相对外壳的 absolute，
        桌面浏览器下居中显示时才不会铺满整屏
     3. H5 自建组件：toast / modal / loading / 客服弹层
     4. 小程序标签的等价物：scroll-view、picker（覆盖式原生日期输入）
     5. 表单元素兜底重置

   注意：页面自身的样式全部来自 assets/pages/*.css（由 wxss 自动转换），
   布局结构全部来自 wxml 编译产物 —— 这一层只补浏览器独有的部分。
