A group of identical skinned-mesh instances drawn in ONE drawIndexed call via
GPU instancing (the skinned shader's HAS_INSTANCING variant). All instances
share mesh, material and a single jointMatrices palette (the identity bind
pose for static level geometry — skinning is then a no-op); only the per-instance
model/normal matrix varies. Collapses a level's reused mesh library (hundreds of
per-node draws) into a handful of instanced draws. No morph targets.
