Generate or edit raster images for the codex repo using Codex's built-in image_gen tool (gpt-image-2, also known as "image gen 2.0"). Use when the user asks for a bitmap asset such as a hero image, mockup, screenshot backdrop, illustration, sprite, marketing visual, or photorealistic render, and wants Codex to create a new image or edit an existing one in the workspace. Do not use for SVG/vector icons, code-native diagrams, or extending an existing vector asset system.
