 Available YOLO26 variants: `yolo26n`, `yolo26s`, `yolo26m`, `yolo26l`, `yolo26x`.
 Smaller variants (`yolo26n`, `yolo26s`) are recommended for high-FPS edge deployment.
-The default tracker is `short-term-imageless` (Kalman filter-based, no image data required).
-DLStreamer also supports `tracking-type=deep-sort` for more robust re-identification using a feature extraction model (e.g., mars-small128).
+The default tracker is BoT-SORT; ByteTrack is available as an alternative with lower computational overhead.
