# Avalonia Bulk Copy dialog (ported from the old project's Copy extension via
# the WPF UI/WPF/Extensions/IntuneManagerBulkCopyUIWPF.ps1). New file per
# architecture rule R9. Thin caller of the public Start-GraphBulkCopy driver
# (R10) — the UI only collects the two name patterns and the selected types.
