The browser-optimized neutral surface was adapted by Sameer Sontakey's
Plethscape project: https://github.com/sontakey/plethscape
Reference commit: 83fcf0ca1d8619afc4e802e1e88d180de75c1578.
Its published adaptations include hand-pose changes, forearm reconstruction,
external reproductive-contour removal, remeshing and browser compression.

Continuum supplies new materials, transparency, camera framing and interaction.

Liver, gut, pancreas, selected muscles and kidneys use 79 BodyParts3D organ
meshes (63,754 triangles), prepared by Human Atlas:

Reference commit: 1c38bf35c254a891200d3cedecfd57abebe83d8d.
The source notice is retained in models/ORGANS_SOURCE_ATTRIBUTION.md.
Continuum extracts the selected meshes and applies one uniform scale
(2.122745644125938) to match the existing body surface. Source positions and
relative proportions are preserved; models/metabolic-organs.json records the
part identifiers, source hashes, and transform. scripts/build_dashboard_organs.py
reproduces the local GLB from the upstream manifest and decoded binary chunks.

Gray organs mean no direct organ measurements are connected to this dashboard.
A lighter gray marks selection, not health or activity. Foreground organs fade
when selecting the pancreas or kidneys so their depth remains visible.
These meshes are reference anatomy, not patient imaging. The model's aggregate
tissue uptake is associated with selected muscles for explanation, not localization.
The CGM marker remains schematic, not a claim about the actual device site.

No Renderpeople scanned heads, brand marks or restricted assets are used.
The sources do not endorse Continuum. Geometry and physiology have separate
provenance: the physiology is the repository's illustrative reduced solver.
