+Windows 桌面壁纸增强工具 — 将 WebView2 嵌入桌面壁纸层，在壁纸上叠加时间、天气、星座运势、AI 资讯等信息卡片。
+
+## 功能
+
+| 模块 | 说明 |
+|------|------|
+| 壁纸 | 6 种主题动画（极光/星空/渐变/粒子/极光流体/文字）、本地图片、Bing 每日壁纸、纯色/渐变 |
+| 时间 | 大字时钟，支持秒显示开关，整点光晕动画，节日倒计时 |
+| 天气 | 和风天气 API，当前天气 + 24h/7d 预报，IP 自动定位 + 手动选城 |
+| 星座运势 | 天聚数行 API，5 维指数进度条 + 幸运标签 + 今日概述 |
+| AI 资讯 | 天聚数行 API，图文布局 5 条展示 |
+| 知识卡片 | AI 生成，自定义关键字 + 提示词 |
+| 桌面设置 | 独立 WebView2 窗口，所有配置可视化操作 |
+

+
+## 架构
+
+```
+┌──────────────┐     ┌─────────────────┐
+│  systray.go  │────▶│  WebView2 主窗口  │ SetParent → WorkerW (壁纸层)
+│  (托盘+消息循环) │     │  overlay.html    │
+└──────┬───────┘     └─────────────────┘
+       │ evalJS / SetHtml
+       │
+       ▼
+┌──────────────┐     ┌─────────────────┐
+│ settings.go  │────▶│  WebView2 设置窗口  │ 独立窗口, 760x1350
+│              │     │  settings.html    │
+└──────────────┘     └─────────────────┘
+```
+
+**核心通信机制**:
+- `evalJS(cmd)` — 通过 channel + PostMessage 向壁纸 WebView 注入 JS
+- `htmlQueue` — 通过 SetHtml 替换整个壁纸 HTML（触发完整重载）
+- WebView2 `Bind` — 设置窗口通过 Go 绑定函数读写配置
+
+**数据刷新策略**:
+- 启动时推送文件缓存（即时显示），后台拉取新数据后替换
+- 星座: 24h / AI 资讯: 2h / 知识卡片: 30min / 天气: 10min / Bing: 4h
+
+## 配置
+
+配置文件: `config/settings.json`（与 exe 同级目录）
+
+| 字段 | 类型 | 默认值 | 说明 |
+|------|------|--------|------|
+| layout | string | "single" | 布局: single(合并卡片) / multi(独立卡片) |
+| wallpaperType | string | "theme" | 壁纸类型: theme/image/bing/color |
+| theme | string | "aurora" | 主题动画 |
+| zodiac | string | "射手座" | 星座 |
+| city | string | "" | 天气城市 ID |
+| showSeconds | bool | false | 显示秒 |
+| hideWallpaper | bool | false | 隐藏壁纸 |
+| hideTime | bool | false | 隐藏时间 |
+| hideWeather | bool | false | 隐藏天气 |
+| hideZodiac | bool | false | 隐藏星座 |
+| hideAINews | bool | false | 隐藏 AI 资讯 |
+| hideKnowledge | bool | false | 隐藏知识卡片 |
+| bingAutoRefresh | bool | false | Bing 每小时自动切换 |
+| knowledgeKeyword | string | "" | 知识卡片关键字 |
+| knowledgePrompt | string | "" | 知识卡片提示词 |
+
+## 构建
+
+```bash
+go build -o u-desktop.exe .
+```
+
+需要 Windows 10+ 和 WebView2 Runtime（Win11 已内置）。
+
+## 依赖
+
+```
+github.com/jchv/go-webview2     # WebView2 绑定
+github.com/getlantern/systray    # 系统托盘
+golang.org/x/sys/windows         # Win32 API
+github.com/anthropics/anthropic-sdk-go  # Claude API (知识卡片)
+```
+
+## 开机自启
+
+注册表 `HKCU\Software\Microsoft\Windows\CurrentVersion\Run\UDesktopWallpaper`
+
+## 技术要点
+
+- WebView2 嵌入桌面壁纸层通过 `SetParent` 到 WorkerW 实现（详见 [docs/wallpaper-embedding.md](docs/wallpaper-embedding.md)）
+- 自定义 Win32 消息循环替代 `wv.Run()`（SetParent 后 Run() 消息路由异常）
+- 全屏应用检测：定时检查前台窗口是否全屏，自动暂停/恢复壁纸渲染
+- 配置变更即时生效：设置窗口通过 evalJS 直接操作壁纸层 DOM，无需重启
