+# 融合桌面组件库窗口重设计规格
+
+## Why
+当前融合桌面组件库窗口（FusedDesktopComponentLibraryWindow）的UI设计较为基础，与Windows 11小组件编辑面板相比，缺乏现代化的交互体验和视觉层次。用户需要一个更直观、更美观的界面来浏览和添加组件到系统桌面（负一屏）。
+
+参考Windows 11小组件编辑面板的设计特点：
+- 左侧分类列表，右侧选中组件的详细预览
+- 大型组件预览区域，让用户清楚看到组件效果
+- 底部明显的"添加"操作按钮
+- 简洁的关闭按钮（X）在右上角
+- 深色主题配合毛玻璃效果
+
+## What Changes
+- **重新设计窗口布局**：从左右分栏（分类列表+组件网格）改为左侧面板+右侧预览区的布局
+- **添加组件详情预览区**：选中组件后右侧显示大尺寸预览和组件信息
+- **优化关闭按钮**：使用标准的X图标按钮，不使用圆形样式
+- **添加底部操作栏**：包含"添加到桌面"主操作按钮和"查找更多组件"链接
+- **复用阑山桌面组件库分类**：使用相同的分类ID、图标和本地化文本
+- **移除搜索功能**：参考Windows 11设计，暂不提供搜索
+
+## Impact
+- 受影响文件：
+  - `LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml`
+  - `LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml.cs`
+  - `LanMountainDesktop/Views/FusedDesktopComponentLibraryControl.axaml`
+  - `LanMountainDesktop/Views/FusedDesktopComponentLibraryControl.axaml.cs`
+  - `LanMountainDesktop/ViewModels/ComponentLibraryWindowViewModel.cs`（可能需要添加新属性）
+
+## ADDED Requirements
+
+### Requirement: 窗口布局重设计
+系统应提供一个类似于Windows 11小组件编辑面板的组件库窗口。
+
+#### Scenario: 窗口整体结构
+- **GIVEN** 用户从托盘菜单打开融合桌面组件库
+- **WHEN** 窗口显示时
+- **THEN** 窗口应呈现：
+  - 顶部标题栏：左侧显示"添加小组件"标题，右侧有关闭按钮（X）
+  - 左侧面板：分类列表（复用阑山桌面组件库的分类和图标）
+  - 右侧主区域：选中组件的大尺寸预览 + 组件信息 + 添加按钮
+  - 底部："查找更多组件"链接
+
+#### Scenario: 分类列表交互
+- **GIVEN** 左侧显示组件分类列表
+- **WHEN** 用户点击某个分类
+- **THEN** 右侧应显示该分类下的第一个组件的预览
+- **AND** 分类项应有选中状态视觉反馈
+- **AND** 分类图标和名称应与阑山桌面组件库保持一致
+
+#### Scenario: 组件预览区
+- **GIVEN** 用户选中一个组件
+- **WHEN** 预览区显示时
+- **THEN** 应显示：
+  - 组件标题（大字号）
+  - 大尺寸组件预览图（接近实际尺寸）
+  - 组件描述/功能说明
+  - 底部"添加到桌面"按钮
+
+#### Scenario: 添加组件操作
+- **GIVEN** 用户查看组件预览
+- **WHEN** 用户点击"添加到桌面"按钮
+- **THEN** 组件应被添加到系统桌面（负一屏）中央
+- **AND** 窗口应关闭
+
+#### Scenario: 关闭按钮样式
+- **GIVEN** 窗口标题栏有关闭按钮
+- **THEN** 关闭按钮应使用标准的X图标
+- **AND** 不使用圆形背景或特殊样式
+- **AND** 使用 `DesignCornerRadiusSm` 动态资源
+
+#### Scenario: 查找更多组件链接
+- **GIVEN** 窗口底部显示"查找更多组件"链接
+- **WHEN** 用户点击该链接
+- **THEN** 应打开设置窗口的插件目录页面（后续将改为插件市场）
+
+## MODIFIED Requirements
+
+### Requirement: 组件列表展示
+原实现使用网格展示所有组件，新实现改为：
+- 左侧列表仅显示分类（复用阑山桌面组件库的分类ID和图标映射）
+- 右侧预览区一次只显示一个组件的详细信息
+- ~~移除搜索功能~~（根据Windows 11设计，暂不提供搜索）
+
+### Requirement: 关闭按钮圆角规范
+原实现关闭按钮使用硬编码 `CornerRadius="18"`，应改为使用动态资源 `DesignCornerRadiusSm`。
+
+### Requirement: 分类图标复用
+分类图标映射应与阑山桌面组件库保持一致：
+- Clock -> Symbol.Clock
+- Date -> Symbol.CalendarDate
+- Weather -> Symbol.WeatherSunny
+- Board -> Symbol.Edit
+- Media -> Symbol.Play
+- Info -> Symbol.Info
+- Calculator -> Symbol.Calculator
+- Study -> Symbol.Hourglass
+- 其他 -> Symbol.Apps
+
+## REMOVED Requirements
+- ~~搜索功能~~：根据Windows 11小组件面板设计，暂不提供搜索功能

 ### UI

-- **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/`

-# 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
+## 预设风格 (Preset Styles)
-- 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
 
-### 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。
+| 风格 (ID) | 名称 (Local) | 组件圆角 (Component) | 设计语义 |
-- 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。
+| **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
+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)**。
-var cornerRadius = Math.Clamp(cellSize * 0.45, 24, 44);
-```
 
-## 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
+> [!TIP]
-- 20px for common buttons
+> **2. 圆角嵌套规则**：
-- 28px for normal glass panels
+> 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：
-- 36px for large containers and windows
+> - 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。
+
+## 常用资源键 (Common Resource Keys)

+- `DesignCornerRadiusMicro`

+# 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。
