        Startup notice shown once on macOS and Linux (and on Windows when
        IM_EXPERIMENTAL_NOTICE=1, so it can be reviewed during development).
        Hosted by Show-ModalForm -HideButtons from
        UI/Avalonia/Extensions/ExperimentalPlatformNoticeAvalonia.ps1, which owns
        every control name below. There is no WPF twin on purpose: the notice
        never renders on Windows, where WPF is the only backend.
