+`YOLO_MAX_DETECTIONS` is forwarded to Ultralytics as `max_det` for each
+prediction call. GeoIntel defaults it to `1000` because building-rich AOIs can
+contain far more than the Ultralytics default of 300 candidate boxes; keeping
+the upstream default would cap recall before QA/QC begins. Operators may lower
+the value for small rasters or raise it for dense urban tiles after reviewing
+runtime and false-positive behavior.
