/* ============================================================
   index.css —— 最终整合版
   ------------------------------------------------------------
   改动说明：
   1. 删除所有未定义的 CSS 变量（var(--gold-gradient)等），改用实际颜色值
   2. 修复 @media 嵌套错误（media 内不能再写 media）
   3. 删除所有重复定义（.goback / .head_top / .video_operate 等）
   4. 导航栏 + 播放页返回条 + 横幅 三色统一为金色系
   5. 播放器下方操作栏收窄、美化
   6. 所有功能样式100%保留
