/* ============================================================
   全站公共「站点外框」样式
   顶部导航栏(header.glass-topbar) + 页脚(footer.glass-footer) + 手机底部 Tab(.mobile-tabbar)
   ------------------------------------------------------------
   来源：app/index/view/default/index/header.html 的内联 <style>（原样抽出，勿手改本文件以外的地方）。
   为什么要抽出来：Neko 首页需要与「产品套餐」页**完全一致**的顶栏与页脚，但又不该把
   header.html 那套 `*{}` 重置、`body{}`、`body.glass-enabled` 一起带进首页（会改掉 Neko 排版）。
   所以把「外框」单独成文件，header.html 与首页都 link 它 —— 一处生效、全站同步。
   改这里 = 同时改所有页面（含首页）。
