About Fibo Lite

Lighter Fibo variant that creates images from a `prompt` or `structured_prompt`, with an optional `image_url` as input. The settings are `seed` (default 7) and `aspect_ratio` among nine values. It has no resolution or step controls, and returns the structured prompt alongside the image.
