+---
+
+## 4. 数据模型变更
+
+### 4.1 WallpaperMediaType 枚举简化
+
+```
+变更前: None | Image | Video
+变更后: None | Image
+```
+
+### 4.2 设置存储兼容性
+
+现有用户设置中如果包含 `Type: "Video"` 的壁纸配置：
+- 应用将无法识别该类型
+- 将回退到纯色背景
+- 用户需要重新选择图片壁纸
+
+---
+
+## 5. 风险评估
+
+### 5.1 潜在风险
+
+| 风险 | 影响 | 缓解措施 |
+|------|------|----------|
+| 现有视频壁纸用户设置失效 | 中 | 应用会自动回退到纯色背景 |
+| 遗漏的视频相关代码引用 | 低 | 编译器会报告未定义类型错误 |
+| 本地化键遗漏 | 低 | 运行时会显示键名而非翻译文本 |
+
+### 5.2 回滚策略
+
+如需回滚，可通过 Git 恢复以下文件：
+- LanMountainDesktop.csproj
+- MainWindow.axaml / .axaml.cs
+- MainWindow.SettingsHardCut.Stubs.cs
+- AppearanceThemeService.cs
+- WallpaperSettingsPage.axaml
+- WallpaperSettingsPageViewModel.cs
+- SettingsContracts.cs
+- SettingsDomainServices.cs
+- zh-CN.json
+
+---

+# 移除视频壁纸功能规格说明书
+
+## Why
+
+当前 LanMountainDesktop 项目包含视频壁纸功能，该功能引入了以下复杂性和依赖：
+1. 引入了 LibVLCSharp.Avalonia、VideoLAN.LibVLC.Windows、VideoLAN.LibVLC.Mac 等重型依赖
+2. 在主窗口中残留大量视频壁纸相关代码和字段
+3. 在设置页面中保留了视频类型选择器和相关 UI 元素
+4. 在本地化文件中保留了视频壁纸相关文本
+5. 增加了应用复杂度和维护成本
+
+用户决定移除该功能以简化代码库。
+
+## What Changes
+
+- 移除 LibVLCSharp.Avalonia 及 VideoLAN.LibVLC.* NuGet 依赖
