Build a single self-contained index.html using three.js (CDN import map) showing an impressive interactive 3D scene of your own free choice (a car, aircraft, weapon, vehicle, mech, anything cool). Model it from primitives in code — no external 3D assets, textures from URLs, or images. Must be beautiful: good lighting, materials, shadows, environment, post-processing if you like. Interactive: OrbitControls drag/zoom plus at least one click interaction (e.g. click parts to animate/open/fire/transform). Works on mobile touch too. Show a small on-screen hint of controls. Write ONLY index.html in the current working directory (overwrite if present). Do not create other files. Do not explain — just write the file, then reply with one short line: DONE path= bytes=.
