+server-26#236: geocode precision must travel with the coordinates.
+
+`_geocode_location` already judged a result by Google's `location_type` but
+returned only {lat, lng}, so a GEOMETRIC_CENTER route centroid and a ROOFTOP
+address drew the same pin. The type is now part of the returned dict, which
+is stored as-is on the call doc and carried unchanged onto the incident pin by
+`incident_correlator._resolve_location_pair`.
+
+Display-only: every correlator read of location_coords indexes ["lat"] and
+["lng"] directly, so the extra key cannot change a correlation decision.
