   站长前台编辑 —— 共享样式（xhj 定制 2026-09-20；2.1.57 从 moments.css 迁来）
   ----------------------------------------------------------------------------
   这一块是**跨页面共享**的：评论管理面板、点赞数浮层、面板里的小按钮。
   留言板（guestbook.html）与瞬间页（moments.html）都用它，逻辑在
   assets/js/xhj-cmt-admin.js。

   放 base.css 的理由：每页都会加载，加一处就够；放 moments.css 的话，
   留言板页根本不引那个文件。页面专属的少部分（.moment-edit-btn、
   .guestbook-admin-bar）各自留在自己的 css 里。

   可见性：入口默认 display:none，脚本探测出后台登录态后给 <html> 加
   .xhj-admin 才显示 —— 匿名访客看到的页面与改动前逐像素一致。

   顶部导航「固定黑字 + 局部阴影/蒙版」—— xhj 定制 2026-09-21（v2.1.61）
   ----------------------------------------------------------------------------
   问题：导航文字 / 分隔符 / 搜索框 / 图标 全部取 var(--color-accent)（跟随主题设置
         的强调色，当前 #665454 灰棕），而首页顶部 header 是透明的，文字直接压在
         壁纸上 ⇒ 换一张壁纸就看不清。
   方案（v2.1.61，推翻 v2.1.60 的整条白底玻璃条）：
     · 不铺满整条白底，只在「文字附近」做处理，避免丑且挡视线；
     · 前景固定近黑（满足「先固定为黑」）；
     · 给文字加一层「白色光晕 + 轻微暗投影」的 text-shadow：暗壁纸上靠白晕托底让
       黑字清晰，亮壁纸上靠暗投影分层——任意壁纸下都始终可读，且只有文字周边有
       阴影，不碰整条顶栏；
     · 搜索框改成「极淡玻璃描边胶囊」（半透明 + 模糊），不再用实心白底；
     · 悬停时每个导航项是各自独立的极淡玻璃底（局部蒙版），不是整条白底。
   范围：全部规则都挂在 [data-theme="light"] 下 —— 暗色模式一行都不碰（维持原状）。
   回滚：整块删除即可（从本注释到文件末尾），别处零依赖。
