/* =============================================================================
 * live-shell.css — 「实时翻译 / 录音中」页面外壳（live-shell 专属）
 *
 * 只作用于 #page-rec 的录音中状态（#rec-active.rec-live / .rec-live 子树）：
 *   - 顶部固定栏（文件夹 / 语言 / 实时状态 / 耳机 TTS / 结束录制）
 *   - 内容区（小标题 + #line-list + #live-bubble + 提示）
 *   - 「↓ 回到实时」按钮
 *   - 固定底部操作栏 #rec-dock（双向开关 / 画中画 / 暂停 + 录音计时）
 *
 * 约定：
 *   - 设计 token 全部用 --lv-* 变量，作用域限定在 #rec-active.rec-live，不污染全局 :root；
 *   - class 一律 lv- 前缀，避免与 styles.css 里同名/裸名样式冲突；
 *   - 深色模式走 document.documentElement[data-theme="dark"]；
 *   - 兼容 Android 10 WebView（Chrome 80）：不使用 :has、inset 简写、gap 作为唯一间距。
 * 卡片/气泡本体由 live-feed.css 负责，这里只做外壳与布局。
