 Retarget prototype (2026-11-04): `tmp/npc-research/makehuman_retarget.py` rotates
 the A-pose arms down (−38°/+38°) and scales them **1.63×** to the contract 0.70 m
 arm, welds the split vertices, smooth-shades, adds the 13-bone contract armature
-with the project's distance-to-bone `_auto_weights`, renames the mesh to
-`npc_base`, and exports `makehuman_retargeted.glb` — **6,444 tris / 7,186 verts**
-(under 8,000), 14 bones, skinned, arm-down, grounded. The proportion warp (1.63×
-arms) is the same class of issue that blocked Quaternius; here it is accepted for
-the body retarget. Remaining: only the `skin` slot is painted — cloth, pants,
-accessory and hair need the clothing/retopology step.
