| """Normalize an external STL (AhmedML / DrivAerML / NASA-CRM) to the EZFlow |
| convention: max-extent L=1, centred at origin, and compute the frontal (y-z |
| projected) reference area for Cd. Reuses the SAME normalizer the training data |
| used (family_to_stl._normalize_and_measure), so the zero-shot geometries enter |
| the model on exactly the same scale as training. |

| Usage: |
| python normalize_external.py <stl_in> <name> <out_dir> |
| Prints one line: NORM <name> Aref=<aref> -> <out_stl> |
