"""
This script is the command-line entrypoint for posture model training.
It loads all configs, starts the posture training pipeline, and prints final output.
This is cleaner than keeping training logic inside notebooks or mixed scripts.
It is also better for MLflow, DAGsHub tracking, and repeatable execution.
