  title: Adobe Firefly Generative Expand Image
  summary: Expand an image beyond its original boundaries with AI and poll the job to completion.
  description: >-
    Runs an Adobe Firefly generative expand operation, growing a source image
    beyond its original canvas and filling the new regions with AI-generated
    content guided by an optional prompt. The workflow submits the asynchronous
    expand job, polls the status endpoint until it reaches a terminal state, and
    branches on the result to return either the expanded output image URLs or
    the error details. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
