   ★ 2026-11-05 移动端修复（viewport 由 width=1400 改为 device-width 后）
   1) index.html 内联样式用 position:relative !important 压掉了 style.css
      里 .nav-actions 的移动抽屉定位 → 抽屉变成 260x844 的相对定位块，
      把 header 撑满整屏。此处以同等 !important + 更靠后的顺序恢复 fixed。
   2) .mobile-menu-toggle 上原有内联 display:none，导致手机上无法打开
      下载/通知/登录抽屉；这里用 !important 覆盖（桌面端仍由
      style.css 的 display:none !important 隐藏）。
   3) 两个开关统一收到顶栏右侧，避免压住下方分类条。
