/* ==========================================================================
   短视频页（/video.html）—— 仿抖音的界面
   --------------------------------------------------------------------------
   配色按抖音官方视觉走：品牌红 #FE2C55、青色 #25F4EE、正文墨色 #161823；
   浅色为主题（抖音网页版默认），深色为可选（侧栏底部切换，记在本地）。
   版式两套自适应：
     · 电脑（≥1024px）左侧栏 216px + 视频区 + 右侧评论区 380px，视频下方是
       作者/文案/操作按钮（横向胶囊）；
     · 平板（768–1023px）收成单列，评论区改成抽屉；
     · 手机（≤767px）全屏一屏一条、上下滑动，右侧竖排操作栏、底部信息条与标签栏。
   这个文件只服务短视频页，不再往 nzep.css 里堆样式。
