+# Avalonia port of the Bulk Delete dialog from
+# UI/WPF/Extensions/IntuneManagerUI.ps1 (Show-GraphBulkDeleteForm).
+# New file because Bulk Delete is a self-contained subsystem and the WPF
+# original sits in the giant IntuneManagerUI file we're trying not to grow
+# further (architecture rule R9).
+#
+# Slice 4c: core Bulk Delete form. Simpler than 4a/4b — no settings-driven
+# defaults, just a name filter + per-group selection + a confirm dialog. The
+# btnDelete handler is a thin caller of the public Start-GraphBulkDelete driver
+# (R10); the confirm prompt is the UI's job. Event handlers use the module-scope
+# $script:_* state pattern + bare module functions (no GetNewClosure / captured
+# locals / $script:UIProvider) so they resolve correctly at click time
+# (see [[avalonia-closure-dynamic-module]]).
