Generate AI image assets directly into the project. Each image is written to the project's own asset storage and registered in its asset manifest; the tool returns the project-relative asset paths (/_cdn/static/...), which only resolve on the app's own domain — reference them in code or set one as the app/PWA icon via update_project_metadata (iconUrl). Use this for PROJECT-SPECIFIC imagery (mascots, tailored illustrations, app/PWA icons, imagery in a particular style); if you already HAVE an image as a local file (generated or downloaded yourself), use upload_asset. To edit or restyle an existing image, or keep a character/product/logo consistent, pass it in reference_images (this project's stored assets only: an outside image or the user's photo goes in with upload_asset / request_user_upload first, then pass the path it returns); the prompt then says what to change or produce from it. Generate BEFORE building the components that use the images.
