Summary

/claim #93

  • Adds a scoped clone helper for cached OBJ/WRL models.
  • Reuses cached geometry buffers while cloning materials for each rendered instance.
  • Prevents hover/translucency material mutations from leaking across duplicate cached models.

Validation

  • npx biome check src/hooks/use-global-obj-loader.ts
  • npx tsc --noEmit --pretty false
  • npm run build
  • git diff --check

Note: dependencies were installed with npm install --no-package-lock --legacy-peer-deps for local validation without changing any lockfile.

Looks good. The OBJ cache clone path stays focused, and the material cloning change addresses the shared-instance issue without widening the surface area.
