## Notes
First core release. Trained ~127k steps without spectral_norm (the v0.1.0 ms2 fade-step counter shows higher numbers but real training is ~127k). Disc loss diverged post-step-80k due to small dataset (~13 unique cores) + no Lipschitz constraint + unconstrained multiscale_disc lowres critic. Generator produces structured outputs (vertical snow-like patterns, blue/white palette) so the Conv3D backbone has learned meaningful features even if the final Dense head is noisy. Backbone usable for transfer learning; v0.2 planned with spectral_norm enabled for a stable retrain.
