echo 📊 Summary:
echo    • JAR: %STIRLING_JAR%
echo    • Runtime: frontend\src-tauri\runtime\jre
echo    • Modules: %MODULES%
echo.
echo 📋 Next steps:
echo    1. cd frontend
echo    2. npm run tauri-build
echo.
echo 💡 Testing:
echo    • Test bundled runtime: frontend\src-tauri\runtime\launch-stirling.bat
echo    • Tauri configuration already updated to include bundled JRE
echo.
echo 💡 Benefits:
echo    • No external JRE dependency
echo    • Smaller distribution size with custom runtime
echo    • Better security with minimal required modules
echo    • Consistent Java version across all deployments
echo.
echo ✅ The application will now run without requiring users to install Java!
