 CI 会在 Release 中提供 Windows / Linux / macOS 的 amd64、arm64 单文件可执行程序。
 
+Windows 本地打包：
+
+```powershell
+.\scripts\build-windows.ps1 -Version dev
+```
+
+Windows 可执行程序使用项目 Logo，不显示控制台窗口；启动后会常驻系统托盘。托盘菜单可打开 MeBox、切换开机自启、查看日志、重启或退出。

 Release builds ship single-file binaries for Windows, Linux, and macOS on amd64 and arm64.
 
+Build the Windows executable locally:

+```powershell
+.\scripts\build-windows.ps1 -Version dev

+
+The Windows executable uses the project logo and runs without a console window. It stays in the notification area, with menu actions for opening MeBox, toggling auto-start, viewing logs, restarting, and exiting.
