/* ── 聊天页内嵌音乐播放器 · 迷你 dock + 展开播放页 ──────────────────────────
   来源:/opt/tidal/max-client/engines/pwa-music-player-mcp/web/player.css
   这是一份【副本】,不是原文件(原文件在播放器仓库里被 git 跟踪,不动它)。改动:
   1. 删掉所有全局样式(html / body / * / ::selection / ::-webkit-scrollbar /
      :focus-visible / 全局 [hidden]),原样照抄会把聊天页搞坏。
   2. 所有选择器全部收进 #musicDock / #musicPanel 里,不碰聊天页任何 class。
   3. 颜色改用聊天页自己的 CSS 变量(--text / --accent / --field-bg …),
      所以 light(珍珠潮汐)和 harbor(深色)两套主题自动跟随。
   4. 删掉 demo 首页(.demo-shell / .intro / .catalog)相关样式,聊天页里用不到。
   5. dock 和展开层【拆成两个兄弟节点】。展开层单独 z=1450 全屏盖住;
      如果把展开层套在 dock 里,dock 的 z-index 会开一个层叠上下文,展开层再高也钻不出去。

   ── v4 补丁(2026-08-29 · 搬到页眉底下)────────────────────────────────
  11. dock 从「输入栏正上方」搬到「页眉正下方」,收起是右上角一颗 28px 小圆钮,
      点开才是一条长条。它现在是 .app 里一块绝对定位的空壳(.app 是 fixed),
      所以聊天怎么滚它都不动,也永远不会跟长高的输入框叠在一起。
  12. 【整段删掉】原来 :root[data-music-active="1"] .scroll 的底部内边距/渐隐蒙版,
      和 :root[data-music-active="1"] #attachBar 那两条「附件缩略图往上抬」——
      播放器不在底部了,这些补丁全是死代码。player.js 里 setDockActive 一并删掉,
      改成往 #musicDock 上写 data-track / data-open / data-sounding。
  13. 圆钮没歌也在(opacity .5,淡一点),有歌变实;正在响的时候封面在圆钮里慢慢转,
      暂停就停(prefers-reduced-motion 下不转)。没歌时点它 = 直接开整屏播放页的曲库。
  14. 材质跟页眉那一层的 .pin-bar / .chain-chip 用同一套变量
      (--card-bg / --card-line / --soft-shadow + backdrop-filter),浅色深色自动跟随。
