It may not have a planetary sky, weather system, or horizon, but it has open air: streets, farms, industrial flats, housing belts, transit plazas, and public districts sitting inside one enormous artificial atmosphere.

Inside that boundary, operators use airflow zoning, fire curtains, contamination shutters, pressure doors, service membranes, and emergency bulkheads to manage faults. Most civic zones are normally open to the shared atmosphere.
