+## 7. UI 重设计（#39 / #40 / #41）
+
+### 7.1 ProfileHeroCard (#39 / #41)
+
+| 元素 | 规格 |
+|------|------|
+| 头像 | 72pt 圆形；无头像时 8 色渐变占位（uid%8） |
+| 昵称 | fontWeight w700，titleMedium |
+| Handle | `@J{uid}`，bodySmall onSurfaceVariant |
+| 手机号 | 掩码 `+CC ***XXXX`，bodySmall |
+| Bio | 非空显示，为空显示「添加一句话简介」（斜体，半透明） |
+| AppBar | compact，右侧：QR 图标 + 编辑铅笔 |
+
+渐变色方案（`_ProfileHeroCard._gradients[uid.abs() % 8]`）：
+```
+0: [#4776E6, #8E54E9]  1: [#11998E, #38EF7D]
+2: [#FC466B, #3F5EFB]  3: [#F7971E, #FFD200]

+6: [#1FA2FF, #12D8FA]  7: [#9D50BB, #6E48AA]
+```
+
+### 7.2 彩色图标行与分组卡片 (#40)
+
+`_IconBox`：36pt 圆角正方形（8pt）白色图标，iOS Settings 风格。

+- `SettingsState.bio: String`（默认 `''`）
+- `SettingsViewModel.loadProfile()` 赋值 `bio: profile.bio`
+- 数据来源：`ProfileResponse.bio` → `GET /app/api/user/profile`
