Modifications by BetterHeart: select ascending aorta, aortic-arch branches, superior vena cava and
upper-limb arteries, veins and nerves (incl. brachial plexus), shoulder-girdle and upper-limb bones, upper-limb
muscles, the flexor retinaculum and the heart walls as a landmark; bake node transforms; weld vertices; rescale
to a shared coordinate system; pack coordinates and indices into arm-meshes.bin
with a descriptive arm-manifest.json; recolor for education. Arterial centreline
routes in arm-routes.json are computed from the atlas vessel surfaces.
The adapted data (arm-meshes.bin, arm-manifest.json, arm-routes.json) is shared

names are retained in arm-manifest.json. Build script: tools/build-assets.mjs.

Blood-flow particles and their timing are original educational schematics,
not patient data.
