/*!
 * 易译 · 实时卡片渲染样式（live-feed）
 * 契约：docs/LIVE_CARDS_CONTRACT.md §2/§4；视觉基准 docs/design_realtime_cards.css
 *
 * 约定：
 *  - class 全部 lv- 前缀，绝不复用设计稿裸名（.card/.livebubble/.wave 等与全局冲突）
 *  - 颜色只读 --lv-* 变量（由 live-shell.css 在 #rec-active.rec-live / .rec-live 作用域定义），
 *    这里保留浅色兜底便于独立预览；深色用 [data-theme="dark"] 组件级覆盖
 *  - 卡片间距由本文件负责（#line-list 内每张卡 12px，最后一张 0；气泡 margin-top:12px），
 *    live-shell 不要给 #line-list 再加 gap，避免双倍间距
 *  - Android 10 WebView（Chrome 80）：不用 :has / inset 简写
