How this model is used in MFA (MF Transformation System)
---------------------------------------------------------
The GLB file is rendered unmodified via Three.js + GLTFLoader inside
each workout-log card and PDF report. Per-mesh colors are tinted at
runtime to highlight the muscles a member trained that session; the
underlying geometry data is never altered or re-exported.

The only MFA file that directly loads and renders this model is:

    public/static/js/shared/body-anatomy-3d.js

That JavaScript integration file is also distributed under CC BY-SA 4.0
(see its file header). All other MFA application code is under MFA's
own license and is intentionally kept separate from the model and its
integration code — the SA obligation does not propagate to unrelated
source files in the repository.

Visible attribution
-------------------
A footer line is displayed under every on-screen and in-report instance
of the 3D model, reading:

    "모델: hpfrei/body-anatomy-3d-viewer · 데이터: Z-Anatomy (CC BY-SA 4.0)"

If you fork MFA and remove the 3D model, you may also remove this file
and the attribution footer. If you keep using the model, the attribution
and ShareAlike obligations remain in force.
