gpt-6.1-sol in Codex CLI 0.156.1

Build a short cinematic camera study in Three.js that demonstrates a dolly zoom, the 'vertigo' shot. A lone figure stands at the end of a long corridor lined with repeating columns, doors and ceiling lights. Over the shot the camera physically travels backward along the corridor while its field of view narrows at the matching rate, so the figure stays exactly the same size and position on screen while the corridor behind it visibly stretches away and then snaps back. Light it with cold overhead fluorescents and a faint fog. Ease the move in and out, then reverse it so the loop closes. The animation plays automatically, fills the window at 16:9, loops seamlessly every 8 seconds with no visible jump at the loop point, and shows a small unobtrusive caption in one corner naming the technique. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as a single self-contained index.html (inline CSS and JS) in the current directory. Three.js may load from a pinned CDN. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.
