   目录:
     1. Design tokens (:root 色板 / 字体 / 尺寸 / 阴影 / 动效)
     2. Base & reset
     3. Utilities (.hidden / focus / 细滚动条 / toast)
     4. Mobile topbar（默认隐藏，<768px 显示）
     5. Sidebar（深暖墨 + 木棉红光晕）
     6. Main & messages（暖纸 + 径向光 / 气泡 / 欢迎区）
     7. Composer（毛玻璃 / 悬浮胶囊 / 录音与识别进度）
     8. Agent panel（卡片化 / Tab 分段 / 族谱表格 / 对话记录）
     9. Animations
    10. Responsive（≥1200 三栏 / 768–1200 抽屉 / <768 移动）
