"""DLC Post-Processing — standalone launcher.

Opens the DeepLabCut post-processing studio in its own window: load DLC
tracking (.h5 / .csv) next to the source video, clean noisy keypoints,
compute kinematics, detect social behaviours, draw ROIs, refine identities,
and export GLM-ready tables and overlay videos.

Run it with::

    python app.py

Everything is local: no network access, no accounts. User settings are
stored under ``~/.dlc_processor/settings.json``.
