/* ================= 导航账号入口：头像 + 账号卡弹层 =================
   导航栏里原来的「用户名 + 退出」文本链，改成：直接显示头像，点头像弹出账号卡。
   账号卡内容：头像/用户名/等级徽章 + 「已加入本站 N 天」 + 当前等级卡（等级名/经验 x/y/进度条）
              + 个人中心 / 我的帖子 + 退出。
   弹层由 js/navaccount.inline.js 在打开时 reparent 到 <body> 并改用 fixed 定位，
   避免被 .nav 的 overflow-x:auto（手机端横向滚动）裁掉，也避开 `.nav a` 的既有样式。 */
