-- [ ] Evaluate raising the per-character glTF vertex cap from 5,000 (and revisit the 6,000-triangle

+- [x] Raise the per-character library cap from 6,000/5,000 to **8,000 triangles / 8,000 glTF
+      vertices** so face, hand-grip and clothing detail is not forced to replace geometry. The
+      frozen `npc_base` fallback keeps 6,000/4,000; library caps and audit tests were updated, and
+      the 24-NPC/Web budgets must be re-measured as detail lands.
 
 - [x] Audit all variants against a shared human proportion guide (head height, shoulder width,
       torso length, hip width, limb length, foot length) and correct the worst outliers.
