/* ==========================================================================
   视频剪辑编辑器 · 增量样式
   复用 editor.css 的全部骨架：顶栏 / 工具栏 / 子菜单 / 快速条 / 右侧面板
   这里补「监视器 + 多轨时间线 + 工作流」的差异部分
   --------------------------------------------------------------------------
   配色分工：
     · 外壳（顶栏 / 左工具 / 右面板 / 底部工作流）= 暖纸浅色，和另外两个编辑器同族
     · 工作区（监视器 / 时间线 / 媒体池）= 暖褐暗色，画面的黑场不刺眼也不脏
