Pinned commit: f0eeb6e843380cfe6b83797cf8c3e1af74de5e61
The source repository converted OBJ geometry to binary STL.

Changes: selected lumbar vertebrae (FMA13072-13076), disks (FMA16033-16037),
sacrum (FMA16202), hip bones (FMA16586-16587); welded duplicate vertices at
0.001 mm precision; converted to indexed binary geometry; recalculated smooth
normals; display orientation, materials and educational color highlights.
No pathological deformation. Adapted geometry and rendered model posters
remain CC BY-SA 2.1 JP. No endorsement by DBCLS or the source authors.
No Anatomy 3D Atlas assets are incorporated.

Binary format: little-endian uint32 vertex count; uint32 index count;
vertexCount*3 float32 positions; indexCount uint32 triangle indices.
Coordinates retain the source frame. The viewer changes orientation only.
Reproducible conversion: website/sitegen/prepare_anatomy.cjs.
Hashes and triangle counts: manifest.json in this directory.
