Heart: generated illustrative external myocardium; artery/valve semantic colors.
Muscles: generated illustrative skeletal muscle and tendon collagen textures.
Lungs: generated illustrative external pleural-surface material.
Vessels: semantic arterial/venous display colors.
These appearances are not patient photographs, histology measurements,
calibrated albedo maps or measured physical tissue parameters. Original PNGs
are embedded byte-for-byte with existing UVs; no new image synthesis or editing.
Full retained prompts, hashes, authors and provenance are in licenses/.

SomaAtlas changes: selected named existing anatomical structures; repackaged
self-contained glTF 2.0 GLBs; embedded existing image bytes; losslessly reduced
index width where possible. Muscle, lung and cardiac triangle connectivity,
vertex positions, normals and texture coordinates are unchanged from sources.
Vascular curves are evaluated with the original authored native controls, radii,
bevel/tessellation settings and positions; their exact triangle meshes are merged
by artery/vein display material without welding. No voxel anatomy, invented
anatomical surfaces, added vessel routes, remeshing or decimation is included.
Coordinates are glTF Y-up metres, +X atlas-left, +Z anterior. No patient or DICOM
registration is implied. Detailed included-structure lists and camera framing
are in the accompanying model JSON files and manifest.json.

GLBs or adaptations; mark changes and share adapted atlas mesh assets under the
