 ### UI
 
 - 主题、资源和视觉语义优先遵守 `docs/VISUAL_SPEC.md` 与 `docs/CORNER_RADIUS_SPEC.md`
-- **组件圆角**：所有内置与插件组件的根边框必须使用 `{DynamicResource DesignCornerRadiusComponent}` 资源。
+- **圆角规范 (AI 强制建议)**：
+    - **桌面组件根容器**：必须且仅能使用 `{DynamicResource DesignCornerRadiusComponent}`。
+    - **内部元素**：必须根据嵌套层级使用 `DesignCornerRadiusSm/Md/Lg` 等 Token，严禁硬编码像素值。
+    - **禁止修改系数**：严禁在圆角资源上乘以任何 `scale` 变量，圆角现在由全局样式固定控制。
 - 设置页相关改动通常同时落在 `Views/`、`ViewModels/`、`Services/` 和 `.trae/specs/`
 - UI 启动与窗口生命周期主线在 `Program.cs` 和 `App.axaml.cs`

-# 圆角设计规范
+# 圆角设计规范 (LanMountain Desktop Corner Radius Spec)
 
-## 中文
+## 核心理念 (Core Philosophy)
 
-本规范用于统一阑山桌面不同层级容器和控件的圆角尺度。
+为了确保桌面组件在不同尺寸、缩放比例下都能保持视觉一致性和美感，阑山桌面采用了 **固定圆角风格预设 (Fixed Corner Radius Styles)**，全面参考小米澎湃OS (Xiaomi HyperOS) 的设计语言。
 
-### 基础层级
+所有的组件和容器必须使用统一的资源键，禁止在 XAML 或代码中使用硬编码的像素值。
 
-- Level 1：12px，小元素和图标容器
-- Level 2：16px，小型色块和紧凑控件
-- Level 3：20px，普通按钮
-- Level 4：24px，输入面板和小型容器
-- Component：18px，桌面组件的标准圆角（默认值）
-- Level 5：28px，普通玻璃面板
-- Level 6：32px，强化容器
-- Level 7：36px，大容器、窗口、任务栏
+## 预设风格 (Preset Styles)
 
-### 使用建议
+用户可以在设置中选择以下四种风格之一。系统会自动根据选中的风格动态映射全局圆角 Token。
 
-- 同层级元素保持相同圆角。
-- 大容器的圆角大于内部子面板。
-- 动态尺寸组件可按 `cellSize` 计算圆角，但仍要落在统一范围内。
+| 风格 (ID) | 名称 (Local) | 组件圆角 (Component) | 设计语义 |
+| :--- | :--- | :--- | :--- |
+| **Sharp** | 锐利 | 20px | 紧凑、精确、利落 |
+| **Balanced** | 平衡 | 24px | **默认值**。和谐、自然、普适 |
+| **Rounded** | 圆润 | 28px | 保守、柔和、亲切 |
+| **Open** | 开放 | 32px | 现代、沉浸、夸张 |
 
-### 动态圆角建议
+## Token 阶梯映射 (Token Step Mapping)
 
-```csharp
-var cornerRadius = Math.Clamp(cellSize * 0.45, 24, 44);
-```
+每个风格都定义了一套完整的圆角阶梯，以确保在大容器包裹小元素时满足 **圆角嵌套一致性 (Nesting Consistency)**。
 
-## English
+| Token | Sharp | Balanced | Rounded | Open | 典型场景 |
+| :--- | :--- | :--- | :--- | :--- | :--- |
+| **Micro** | 4px | 6px | 8px | 10px | 小图标容器、角标 (Badge) |
+| **Xs** | 8px | 12px | 14px | 16px | 小标签 (Tag)、输入框 |
+| **Sm** | 10px | 14px | 16px | 20px | 普通按钮、搜索栏、复选框 |
+| **Md** | 14px | 20px | 24px | 28px | 悬浮菜单、小提示框、子卡片 |
+| **Lg** | 20px | 28px | 32px | 36px | 普通面板、对话框内容区 |
+| **Xl** | 24px | 32px | 36px | 40px | 大尺寸容器、设置中心页面 |
+| **Island** | 28px | 36px | 40px | 44px | 任务栏、全局大悬浮容器 |
+| **Component** | **20px** | **24px** | **28px** | **32px** | **所有桌面组件 (Widget) 的主边框** |
 
-This specification keeps corner radius usage consistent across containers and controls.
+## 开发准则 (Implementation Rules)
 
-### Reference levels
+> [!IMPORTANT]
+> **1. 桌面组件强制约束**：
+> 所有桌面组件（Widget / Desktop Component）的根容器边框必须使用 `{DynamicResource DesignCornerRadiusComponent}`。严禁对其进行任何比例运算或系数乘积（如 `* scale`），必须保持固定。
 
-- 12px for small elements
-- 20px for common buttons
-- 28px for normal glass panels
-- 36px for large containers and windows
+> [!TIP]
+> **2. 圆角嵌套规则**：
+> 当一个容器包裹另一个元素时，外层圆角应比内层圆角大一个阶梯。例如：
+> - 外部使用 `DesignCornerRadiusLg`
+> - 内部紧贴边缘的内容应使用 `DesignCornerRadiusMd`
+> 这样可以保证两条圆弧的圆心趋于重合，视觉重心更稳固。
+
+> [!CAUTION]
+> **3. 禁止硬编码 (No Hardcoding)**：
+> 禁止写死数字（如 `CornerRadius="24"`）或私有资源。如果现有 Token 无法满足需求，应优先考虑使用 `SafeValue` 辅助方法封装，但必须声明理由。

+# 字体排版设计规范 (Typography Specification)
+
+## 中文
+
+本规范用于统一阑山桌面各组件（Widget）及页面的字体样式，解决目前组件间字体不协调、厚度不一的问题。通过引入标准化的设计 Token，确保在不同 DPI 和设备上呈现一致的高级感（Premium Look）。
+
+### 1. 字体家族 (Font Family)
+
+- **默认字体**：优先使用内置的 `MiSans VF` (Variable Font)。
+- **回退顺序**：`MiSans VF` -> `MiSans` -> `Microsoft YaHei` -> `Sans-serif`。
+
+### 2. 字重标准 (Font Weights)
+
+为了达到“不粗不细”的协调感，我们采用 `Medium (500)` 作为默认正文字重，以应对复杂的背景环境。
+
+| 角色 | Token | MiSans 权重 | 说明 |
+| --- | --- | --- | --- |
+| **Caption/Secondary** | `DesignFontWeightCaption` | `Normal (400)` | 用于不重要的补充说明信息 |
+| **Body (Default)** | `DesignFontWeightBody` | `Medium (500)` | **核心全局字重**，用于所有常规正文 |
+| **Title/Header** | `DesignFontWeightTitle` | `SemiBold (600)` | 用于卡片标题、分类标题 |
+| **Display (Large)** | `DesignFontWeightDisplay` | `SemiBold (600)` | 用于超大号文本（如温度数字） |
+
+> **注意**：除非极特殊艺术需求，应避免使用 `Thin`, `ExtraLight`, `Light` 或 `Bold (700)`, `Heavy`。
+
+### 3. 字号标准 (Font Sizes)
+
+| 角色 | Token | 数值 (px) | 典型应用场景 |
+| --- | --- | --- | --- |
+| **Caption** | `DesignFontSizeCaption` | 12 | 底部说明、状态提示 |
+| **BodySmall** | `DesignFontSizeBodySmall` | 13 | 设置项描述、次要标签 |
+| **Body** | `DesignFontSizeBody` | 14 | 标准文本、正文内容 |
+| **BodyLarge** | `DesignFontSizeBodyLarge` | 16 | 加大正文、菜单项 |
+| **Subtitle** | `DesignFontSizeSubtitle` | 18 | 小节标题、大按钮文字 |
+| **Title** | `DesignFontSizeTitle` | 24 | 组件标题、大卡片标题 |
+| **Headline** | `DesignFontSizeHeadline` | 32 | 重要数据指标 |
+| **Display** | `DesignFontSizeDisplay` | 48 | 天气温度、时间分钟 |
+| **DisplayLarge** | `DesignFontSizeDisplayLarge` | 54 | 诗词正文、欢迎语 |
+
+### 4. 行高标准 (Line Heights)
+
+统一行高可以增强视觉节奏感。
+
+| Token | 数值 (倍率) | 应用场景 |
+| --- | --- | --- |
+| `DesignLineHeightStandard` | 1.2 | 单行标签、紧凑卡片 |
+| `DesignLineHeightLoose` | 1.5 | 多行诗词、新闻摘要、说明文档 |
+
+### 5. 使用规范
+
+1. **禁止硬编码**：严禁在 `.axaml` 中直接写入 `FontSize="18"` 或 `FontWeight="Bold"`。
+2. **动态资源绑定**：始终使用 `{DynamicResource DesignFontSize...}` 进行绑定。
+3. **全局样式继承**：`App.axaml` 已经设置了 `TextBlock` 的默认 `FontWeight` 为 `Medium`，除非是 `Caption` 或 `Title`，否则无需重复声明。
+
+---
+
+## English (Summary)
+
+- **Default Font**: MiSans VF.
+- **Base Weight**: `Medium (500)` for better readability on glass/dark backgrounds.
+- **Header Weight**: `SemiBold (600)` for a modern premium feel.
+- **Line Height**: Standardized to 1.2x and 1.5x.
+- **Tokens**: All components must use `DesignFontSize...` and `DesignFontWeight...` resource keys.
