 # MarketAssistant UI 设计系统
 
-> **版本**: 2.0  
+> **版本**: 2.1  
 > **平台**: Avalonia 11.x 跨平台桌面应用  
 > **产品**: 金融市场数据终端 (A股 + 虚拟币)  
 > **设计方向**: 清晰专业风 — Bloomberg Terminal 的严谨 × 现代 SaaS 的优雅
+>
+> **v2.1 变更（与 design-prototype.html v5 的裁决）**：
+> 1. 深色背景以本文档色值为准（`bg-root #0A0E17` / `bg-surface #111722` / `bg-elevated #161C2A`），原型中更深的 `#080C14/#0E1320/#141B2A` 弃用；
+> 2. 导航活跃指示条采用**左侧 3px 竖条**，不采用原型的底部横条；选中项背景使用 `bg-selected` 浅色填充而非整块品牌蓝；
+> 3. 首页不放 K 线区，采用 Bento Grid（热门标的置左最宽 + 快讯 + 最近查看）；K 线保留在资产详情页。原型中的"AI 市场概览横幅"待数据源就绪后再引入；
+> 4. 涨跌标签一律带约 12% 透明度背景（`BullishTagBackgroundBrush` 等），靠色块而非纯文字色区分语义；
+> 5. 响应式简化为两档：≥1100px 完整布局，<1100px 单列隐藏详情面板；
+> 6. TopBar 常驻：标题/返回 + A股/虚拟币分段切换器（复用 Ctrl+M 同一逻辑）；行情 ticker 需真实指数数据源，无数据时整段隐藏。
