+# Attaches LoadIconImage / GetImage to every IntunePolicyType + IntunePolicyGroup
+# singleton so left-nav menu items (and downstream consumers via $item.IconImage)
+# get a real Avalonia visual instead of $null.
+#
+# Two divergences from the WPF original:
+#   1. File extension is .axaml (the converter under XAML/Icons/_Convert-Icons.ps1
+#      writes Avalonia-flavoured copies of the WPF .xaml shape sources).
+#   2. Get-XamlObject here is the Avalonia loader (Extensions/CoreUI.ps1), so
+#      the Image returned is an Avalonia Viewbox/Canvas tree that the
+#      lstMenuItems DataTemplate's <ContentControl Content="{Binding IconImage}"/>
+#      can host directly — no WPF→Avalonia conversion at runtime.
