Image Studio
Create polished raster images with Codex's built-in image_gen tool. Never call LabNana, Gemini, OpenAI API/CLI, a local generation script, or any other external image provider. Do not require or request an API key.
If the runtime does not expose the built-in image_gen tool, stop and explain that image generation requires Codex with built-in image generation. Do not silently downgrade or insert a placeholder.
