+# Scoped policy picker (WPF).
+#
+# Thin wrapper over Show-ObjectPickerDialog: it supplies the tenant list, the
+# scope list and a search handler, so the dialog queries Graph for the typed
+# name inside the selected policy group / policy type instead of enumerating the
+# whole tenant up front. The search itself lives in Internal/PolicySearch.ps1
+# and is shared with the Avalonia backend (R10 - this file only collects input
+# and renders).
