    TeamsISO — MSI installer (WiX v5)

    Produces: TeamsISO-Setup-<Version>.msi (per-machine install).

    Build:
        dotnet publish src/TeamsISO.App/TeamsISO.App.csproj -c Release -r win-x64 (no self contained) -o publish/TeamsISO
        dotnet build installer/TeamsISO.Installer.wixproj -c Release

    Runtime expectations:
        - .NET 8 Desktop runtime present on target (framework-dependent build)
        - NDI 6 Runtime present — checked in CheckNdiRuntime; absence WARNS
          but does not block install (operators can install NDI after the app)

        NDI runtime detection is surfaced at first app launch (App.xaml.cs pops a
        MessageBox with an install link). We deliberately don't block install on
        a missing runtime so admins can stage the app before NDI is rolled out.
        VBScript-based install-time prompts are deprecated in WiX v5 / Windows
        and rewriting in C++ is overkill for a soft warning.
