/* ============================================================================
   时间轴层叠修复（v1.14）
   ----------------------------------------------------------------------------
   问题根因：
   1) `.tl-row:hover .tl-head` / `.tl-row.tl-group>.tl-head` 用「半透明色」
      覆盖了原本不透明的 `var(--p1)` 背景 —— 鼠标一悬停，表头就变成半透明，
      横向滚动到表头下面的片段（字幕文字等）便直接透出来，把折叠箭头压得看不清。
      改为：底色始终 var(--p1) 不透明，悬停/分组的着色用 background-image 叠一层，
      不再替换 background-color。
   2) 表头 z-index(8) 与播放头(7)/参考线(6) 数值太接近，且 `.tl-row-drag{opacity}`
      会让整行生成新的层叠上下文、把表头的 z-index 关进去，于是拖拽时播放头会画到
      表头上面。改为：内容层 0~9，表头 20，标尺行 30，并把拖拽的半透明改到子元素上。
