  - `team_name` string, required
  - `email` string, required
  - `role` 'owner' | 'billing' | 'admin' | 'editor' | 'viewer', required: Team member roles with hierarchical permissions. Wire DTO mirror of the ORM ``TeamRoleType`` enum. Used only for API request/response serialization; authorization decisions route through the ORM matrix (``database_tables.permissions``), never this enum.
