This is a one-shot benchmark. Work autonomously and do not ask questions. Create the complete final artifact as index.html in the current empty directory. There will be no second attempt and no feedback-driven corrections. You may test and inspect your own work during this single run. The artifact must open directly in a modern browser without a build step. CDN imports for Three.js are allowed, but do not use external models, textures, images, or other content assets.
