This viewer is practical, not "complete USD rendering":

What Works	What Doesn't
✅ Basic geometry (meshes, transforms)	❌ Not a Hydra implementation
✅ UsdPreviewSurface materials	❌ Complex material networks
✅ Common texture setups	❌ Procedural textures
✅ Simple skeletal animation	❌ Full UsdSkel parity
