Detailed Description

Shared geometry metadata for instanced rendering with LOD support.

Each entry describes one unique mesh primitive stored in shared geometry buffers. Instances reference this table through InstanceData::meshGeometryId. Layout matches GLSL std430 MeshGeometryData and is 96 bytes.

Phase C (bindless geometry): payload ranges are referenced by device addresses instead of shared-buffer start indices, so a slot can own its own vertex/triangle/meshlet/bone/LOD buffers. A zero address means the range is not present for this geometry.
