+MakeHuman is therefore **feasible only as a separate local body-shape pipeline**.
+The boundary for that future work is:
+
+- MPFB/MakeHuman is installed and run by a contributor, never by CI or the game
+  build.
+- Generated bodies and intermediate exports stay in `tmp/` (gitignored); the
+  CC0 base mesh is not committed.
+- The contributor scales to 1.8–1.9 m, decimates or retopologises to roughly
+  6–7k triangles, and checks the silhouette against `npc-visual-review.md`.
+- The body gets the contract armature, weights, project-owned head/hands,
+  clothing and gear; it must pass `blender_assets.py audit` and `fit`.
+- Only the final CC0-derived GLB and its provenance note are committed. The
+  application code and any non-CC0 assets stay outside the repository.
+
+This is deferred; it is not part of the 0.11.0 crowd-variety work.
