"""rgthree custom-node metadata extractor (Blueprint example).

This is a minimal scaffold provided to illustrate how a YAML-manifest
blueprint plugin is shaped. It returns an empty success result and is
intended as a copy-and-modify starting point — extend the ``extract``
method with the actual rgthree parsing logic before relying on it.
