photocraft/packaging/windows/package.ps1

<#
.SYNOPSIS
  Build, sign and package PhotoCraft for Windows.

.DESCRIPTION
  Produces, in $env:DIST (default: dist/release):
    photocraft-<version>-windows-<arch>.msi            per-machine installer (WiX v5)
    photocraft-<version>-windows-<arch>-portable.zip   photocraft.exe + photocraft-cli.exe + portable.txt

  The binaries link the C runtime statically (+crt-static), so neither the MSI nor the portable
  zip needs the Visual C++ redistributable. Signing is delegated to sign.ps1 (skipped with a
  warning when no signing secrets are set).

  Needs: Rust (MSVC toolchain + the target), the Windows SDK (rc.exe, signtool.exe),
  and WiX v5: dotnet tool install --global wix --version 5.0.2

.EXAMPLE
  pwsh packaging/windows/package.ps1 -Arch x64
  pwsh packaging/windows/package.ps1 -Arch x86 -SkipBuild
  pwsh packaging/windows/package.ps1 -Arch arm64     # cross-compiled; needs the MSVC ARM64 build tools
#>
