/* ============================================================================
   中旭文化 · H5 App 壳（对齐微信小程序）
   ────────────────────────────────────────────────────────────────────────────
   目标：H5 前台（**报名页 register.html 除外**）在手机上呈现小程序同款形态
         ① 顶部深棕导航栏（替代 PC 的 .navbar）
         ② 底部固定 TAB：首页 / 课程 / [中旭印章 FAB] / 资讯 / 我的
         ③ 内页（课程详情、资讯详情、关于我们…）无 TAB，改为「返回 + 标题」
   作用域：全部规则挂在 `body.zx-app-on` 下 —— 由 app-shell.js 在移动端
          （或 URL 带 ?app=1 强制）才添加。**桌面端不加该类 ⇒ 原 PC 站零影响**。
   数值来源：小程序 custom-tab-bar/index.wxss、pages/index/index.wxss，
           rpx ÷ 2 = px（750 设计宽）。
