PENGWIN Task 1 (CT pelvic fracture segmentation) originates from the PENGWIN
2024 challenge (MICCAI 2024) and is distributed by the challenge organizers via
Zenodo record 10927452.

LICENSE NOTE -- the upstream sources disagree:
  * The Zenodo record metadata declares  CC BY 4.0  (license id "cc-by-4.0",
    access_right "open").
  * The challenge report states the CT training set is released under
    CC BY-NC-SA.

This mirror adopts the more restrictive, author-stated CC BY-NC-SA 4.0 so that
downstream use is safe under either reading. Users who need commercial or
non-ShareAlike terms should consult the Zenodo record and contact the organizers
directly rather than relying on this mirror's choice.

This mirror redistributes the released training split. The .mha files are
rewritten with lossless zlib compression; voxel data, dtype, spacing, origin and
direction are bit-identical to the Zenodo originals (verified on all 200 files).
