How do admins draw geo-fenced delivery zones on a map?

Admins define delivery zones on a map interface, drawing each zone as a polygon. The zone stores the drawn polygon plus a bounding box and centroid (for fast lookup), and an active flag. Drawing zones visually means an operator can carve up a city or region exactly the way their delivery reality works — neighbourhood by neighbourhood — rather than relying on crude radius circles.

Admins define delivery zones on a map interface, drawing each zone as a polygon. The zone stores the drawn polygon plus a bounding box and centroid (for fast lookup), and an active flag.
