+REM Build dsh-launcher.exe for Windows (amd64).
+REM
+REM 用法: scripts\build-windows.bat
+REM
+REM 前置依赖(Windows 上装好后):
+REM   - Go 1.21+                  https://go.dev/dl/
+REM   - Node.js 18+               https://nodejs.org/
+REM   - Wails CLI                 go install github.com/wailsapp/wails/v2/cmd/wails@latest
+REM   - WebView2 Runtime          Win10 1803+ 自带,否则 https://aka.ms/webview2
+REM   - MSVC build tools          https://visualstudio.microsoft.com/downloads/ (Build Tools for Visual Studio, 勾选 "Desktop development with C++")
+REM
+REM 注意: Wails v2 的 Windows build 需要 MSVC toolchain (cgo 编译 webview2 loader)。
+REM 不能在 macOS / Linux 上 cross-compile 出 .exe。
