+- [Cloudflare] Fix ``list_record_types`` advertising the unsupported ``URL``
+  record type instead of ``LOC``. The ``RECORD_TYPE_MAP`` entry was keyed on
+  ``RecordType.URL`` while its value was ``"LOC"``; the key is now
+  ``RecordType.LOC`` so Cloudflare's supported ``LOC`` record type is reported
+  and the unsupported ``URL`` type is not.
