    `seg=18/rings=12` with small offsets — not missing geometry. Concrete next step, if funded:
    a single-variant `npc_casual` prototype that raises head subdivision and deepens the
    cheek/brow offsets, then re-bakes AO and captures the portrait before touching the other seven.

+   **Prototype landed 2026-11-03/04:** `npc_casual` now has `seg=24/rings=16` (smoother), a subtle
+   brow ridge, a fuller lower lip and both eyelids (upper + lower); recessed creases (nasolabial,
+   temple, chin cleft) were rejected because they bake as dark AO patches. Vision-reviewed: the new
+   face reads cleaner and more realistic than the old (set-in eyes, brow break, lip volume, no
+   faceting); tris 4,482 → 5,038 (still under 8,000). The other seven variants keep the old face
+   until this prototype is approved.
 2. **No pose/weight evidence (unknown).** Idle, walk, sit, block and turn deformation has never been
    captured as a review set, so shoulder/hip/neck collapse is unmeasured. Cheap to add and it
    gates any claim that the rig is acceptable.
