+
+## 评审总结
+
+Phase 3 原型质量**极高**，完整覆盖了 PRD 中所有 P0 (4/4) 和 P1 (19/19) 功能需求。
+
+**亮点**:
+1. 管理后台 4 个子页面布局一致，Sidebar 导航交互正确
+2. 仪表盘图表使用真实感 Mock 数据（折线图有自然波动，排行榜递减合理）
+3. 用户管理交互完整：表格 + 搜索 + 筛选 + 编辑模态框 + 详情抽屉
+4. 个人中心环形进度条 + Sparkline 趋势图 + 配额警告横幅，信息层次清晰
+5. 整体深色主题统一，Linear/Vercel 风格专业感强
+6. 所有页面计量单位正确使用「秒数」（非「次数」），与 Phase 3 需求一致
+
+**可改进项** (不影响通过):
+- P2: Sidebar 折叠模式未实现
+- P2: 骨架屏加载态未实现
+- 用户表格缺少头像列（可在开发阶段补充）
