REM Double-clicking a .bat file can start it with an arbitrary working

REM Optional first argument allows CI or a developer to choose another output

REM Fyne uses native libraries through CGO. MSYS2 UCRT64 provides the GCC toolchain
REM expected by the Windows build; prepending it keeps the script self-contained
REM without permanently changing the user's system PATH.

REM windres embeds the .ico file into the PE executable so Windows Explorer,
REM shortcuts, and the taskbar can show the GoSentry icon. The Go embed package
REM handles Fyne's runtime icon, but Explorer reads this Windows resource instead.

REM -trimpath removes local machine paths from the binary, -s -w reduce binary
REM size, and -H=windowsgui prevents a separate console window from opening when
REM the GUI app starts from Explorer or a shortcut.

REM Icons are embedded into the executable, so no assets directory is copied next
REM to the binary. Runtime YAML and log files are created by the app itself.
