                        Train a deep learning model that grades cards directly from pixels — no CV features needed.
                        More accurate than the feature-based model once you have 500+ labeled images.
                        Uses your Apple Silicon GPU (MPS) automatically.

                        The more labeled cards you have, the better it learns.
