/* ==========================================================================
   comment.css —— 评论 UI 的唯一业务样式层
   ==========================================================================

   为什么放在项目根的 static/ 而不是某个 app：
     首页（app_picllery）与个人页沉浸查看器（app_users）各有一套评论面板，
     两页不共载页面 CSS。放在任一 app 都会让另一页反向依赖它。根 static/
     是项目预留的跨 app 共享目录（dialog.css / dialog.js 已在这里）。

   加载顺序铁律：dialog.css → comment.css → 页面 CSS（index.css / profile.css）。
     comment.css 只写 .cmt-* 与评论面板自己的 --cmt-* token；旧 .comment-* /
     .immersive-comment-* 规则必须从页面 CSS 删除，否则它们晚于本文件加载、
     同特异性，会把新样式静默压回去。

   形态：沿用 .dlg-scrim + .dlg-panel.dlg-panel--fill 的底部抽屉，不改弹窗基类。
   显隐唯一真相源仍是 [aria-hidden]（dialog.js）；本文件只管内容。

   ⚠️ 本文件不得出现「静态资源引用」语法（注释里也不行）：
      Django 的 ManifestStaticFilesStorage 大小写不敏感地解析它，
     注释里的同样会导致 collectstatic 中断（2026-10-11 事故）。
     本文件的 Noto Emoji 全部走 `<img>`，CSS 里没有任何静态资源引用。
