Optimize realtime charts for tablet

- Remove drop-shadow filters on SVG paths on mobile (SignalChart, SummaryCurve)
- Hide scan-haze overlay (mix-blend-mode: screen) on mobile
- Remove feTurbulence noise filter on mobile (biggest perf win)
- Simplify backgrounds and box-shadows on mobile
- Remove blur transition on inactive panels
- Hide window control buttons (minimize/maximize/close) on mobile
- Configure Android release build to sign with debug keystore
- Update README with changelog and Android build instructions

 ## 环境要求
 
 - Node.js 18+（建议 LTS）
 - Rust stable（`rustup` + `cargo`）
 - Windows 下请确保已安装 WebView2 Runtime 和 MSVC C++ 构建工具
+- Android 构建需要 Android SDK + NDK
 
 ## 安装依赖
 
@@ -42,12 +43,61 @@ npm run build
 npm run tauri build
 ```
 
+构建 Android APK / AAB：
+
+```sh
+npx tauri android build
+```
+
+产物路径：
+- APK: `src-tauri/gen/android/app/build/outputs/apk/universal/release/app-universal-release.apk`
+- AAB: `src-tauri/gen/android/app/build/outputs/bundle/universalRelease/app-universal-release.aab`
+
+Release APK 默认使用 debug keystore 签名（`src-tauri/gen/android/app/je-skin-debug.keystore`），可直接 `adb install` 到设备。
+
 ## 代码检查
 
 ```sh
 npm run check
 ```
 
+## v0.5.0 修改记录
+
+### Android USB 串口接入
+
+- **Tauri 插件注册**：Android 端通过 Rust builder 注册 `usb-serial` 插件，移除 `MainActivity` 中的手动加载逻辑
+- **USB 设备枚举**：使用 `usb-serial-for-android` 的 `UsbSerialProber` 识别串口设备，并返回设备名、厂商 ID、产品 ID、权限状态等信息
+- **USB 权限申请**：完善 Android USB 授权回调，支持按设备名、vendorId/productId 解析设备并处理授权后的打开流程
+- **串口数据桥接**：Kotlin 端打开 USB serial port 后通过 Unix socketpair 将 fd 交给 Rust，Rust 端继续复用 `serial_connect_fd` 数据采集链路
+- **资源释放**：关闭连接时同步释放桥接 fd、USB serial port 和 `UsbDeviceConnection`，避免重复打开后的资源残留
+
+### Tauri 权限与构建
+
+- 新增 `src-tauri/permissions/usb-serial/default.toml`，声明 Android USB serial 插件命令和前端所需本地命令权限
+- `default.json` 增加 USB serial 与本地命令权限，兼容 snake_case / camelCase 插件命令名
+- Android Gradle 仓库加入 JitPack，用于解析 USB serial 驱动依赖
+- ProGuard 增加 Tauri 插件注解、`UsbSerialPlugin` 和 `com.hoho.android.usbserial` 保留规则，避免 release 包混淆后插件命令失效
+- Android 构建下 `serial_enum` 返回空列表，并仅保留 fd 连接入口，避免桌面串口枚举依赖进入 Android 编译路径
+
+## v0.4.0 修改记录
+
+### 移动端性能优化
+
+- **SignalChart / SummaryCurve**：在 `@media (max-width: 900px)` 下移除 SVG 路径上的 `filter: drop-shadow()`，避免移动端 GPU 软件回流导致卡顿
+- **SignalChart**：隐藏 `.scan-haze`（`mix-blend-mode: screen` 合成开销大），简化面板 `background` / `box-shadow`
+- **SummaryCurve**：移动端移除 `.summary-line` 和 `.summary-dot` 的 drop-shadow 滤镜
+- **页面级**：移动端隐藏 `.hud-noise`（`feTurbulence` SVG 滤镜是最大性能杀手），降低 `.hud-vignette` 透明度，简化 `.hud-gradient`
+- 移除 inactive 面板的 `filter: blur()` 过渡动画
+- 移除 transition 中的 `filter` 属性，添加 `will-change: d` 优化路径更新
+
+### 移动端 UI 调整
+
+- **隐藏三大金刚**：`@media (max-width: 900px)` 下隐藏标题栏右侧的最小化/最大化/关闭按钮（Android 系统自带窗口管理）
+
+### Android 打包
+
+- Release 构建配置使用 debug keystore 签名，输出签名 APK 而非 unsigned

-- Preferred: `static/models/je-skin-model.glb`
-- Format: glTF 2.0 `.glb`
-- Also supported after changing `modelUrl`: glTF 2.0 `.gltf` with its `.bin` and texture files in the same folder
-- Not supported directly: older glTF 1.0 assets. Convert them to glTF 2.0 first.
