 ## Do Not Forget
 R10 requires trained model — run python scripts/train_retention_model.py first
-RetentionCurvePredictor model saved at viral_script_engine/retention/model.joblib
-MODEL_PATH is Path(__file__).parent / "model.joblib" (relative to curve_predictor.py)
-R10 gracefully skips (score=None) in env.step() if model not trained
