Garry Tan d9b6bf1ff9 feat: design tools prototype validation — GPT Image API works ... Prototype script sends 3 design briefs to OpenAI Responses API with image_generation tool. Results: dashboard (47s, 2.1MB), landing page (42s, 1.3MB), settings page (37s, 1.3MB) all produce real, implementable UI mockups with accurate text rendering and clean layouts. Key finding: Codex OAuth tokens lack image generation scopes. Direct API key (sk-proj-*) required, stored in ~/.gstack/openai.json.
