Configuration
Config (dataclasses in parameter_models.py) is constructed from hardcoded defaults by load_default_parameters_config(), which can alternatively read a JSON file. Defaults include reduce_shakiness.recording_fps = 30.0 (overridden whenever the timestamps CSV yields a real framerate), add_rig.keep_symmetry = False, add_rig.add_fingers_constraints = True, add_rig.use_limit_rotation = False, and alignment reference points (left_knee, left_foot_index) in AdjustEmpties. Only the reduce_shakiness and add_rig sections are consulted by the current MainController pipeline; the other sections are carried but unused there.
