Found the best way to build insane UIs with Codex. ChatGPT isn't as good as Claude at UI, but ChatGPT Images 2.5 is genuinely excellent. The workflow: → Describe what you want → Let it generate a reference image in the background → Hand that image to Codex to build from Try the same prompt with and without this and compare. Results speak for themselves.
