Changes for IKCode: selected visible anatomical regions, reduced mesh density using meshoptimizer, mirrored the supplied left hemisphere to form the right hemisphere, normalized and reoriented geometry, added custom colors and lighting. The truncated lower brainstem is elongated in the runtime geometry for the illustrative side silhouette. This is a stylized anatomical visualization with mirrored hemispheres, not a diagnostic model.
