Z-Anatomy's own README lists the "Kidney" model (Lissie Cowley) as CC BY-NC 4.0, which is not compatible with CC BY-SA publication.
Therefore the atlas kidney meshes are NOT used here: they were removed from lipid-body.bin/json (2026-11-01) and the two kidneys
are drawn by BetterHeart as a schematic in lipid-kidney.js (kidneys with hilum, adrenal glands, renal arteries/veins,
renal pelves and ureters, placed against the atlas aorta and IVC).

Modifications by BetterHeart: select the liver (kidneys excluded, see above), gallbladder, stomach, small and large
intestine, pancreas, spleen, lungs, greater omentum, heart chambers, the aorta and
its coeliac / mesenteric / iliac / femoral branches, the venae cavae, portal, hepatic,
brachiocephalic, subclavian and jugular veins, right thigh muscles and trunk / pelvic bones;
bake node transforms; weld vertices; rescale; compute vessel centre-lines; pack into
lipid-body.bin with lipid-body.json; recolor and render semi-transparently for education.
The thoracic duct and cisterna chyli are not part of the atlas: they are drawn by BetterHeart
along the front of the atlas vertebrae as an educational schematic.
