artwork: Character. Artwork UUID (format: "99xxxxxx-xxxx-xxxx-xxxxxxxxxxxx"). Validated with artcore::validate_uuid() where applicable.
cn: Database connection. If NULL, creates a connection via artcore::dbc() and closes it on exit. Pass an existing connection to batch multiple queries efficiently.
