# ─── Bulk Scope Tags ──────────────────────────────────────────────────────────
# Thin UI wrapper around Set-GraphBulkScopeTags. The form mirrors Bulk Export's
# Group / API selector for picking object types, adds an action selector
# (Add / Replace / Remove), an orphan-cleanup checkbox, and a dual-list scope
# tag picker. All business logic lives in the public command — the UI only
# collects inputs, calls it, and shows the summary.
# Get-BulkScopeTagCatalog moved to Internal/IntuneScopeTags.ps1 so the
# Avalonia tree can share it.
