The prompt

Build a Three.js scene: A red and cream vintage biplane performs loops, barrel rolls and a hammerhead over a grassy airfield, trailing white smoke ribbons that persist and slowly fade. Its propeller spins as a motion-blurred disc and the ailerons visibly deflect during rolls. Pressing keys 1-3 selects the next manoeuvre, and the camera tracks the plane from the ground like a spectator. Use a bright blue summer sky with puffy instanced clouds. Everything is built in code from Three.js geometry, materials and shaders; no external models, textures or fonts. The scene must visibly animate from the moment it loads and run in a browser with software WebGL (no GPU). Deliver ONE self-contained HTML file; load Three.js only through an import map from https://cdn.jsdelivr.net/npm/three@0.170.0/build/three.module.js (addons from https://cdn.jsdelivr.net/npm/three@0.170.0/examples/jsm/), with no other external requests. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.
