  title: Adobe Firefly Generate Similar Images
  summary: Generate variations similar to a reference image and poll the async job to completion.
  description: >-
    Generates images that are visually similar to a provided reference image
    using the asynchronous Adobe Firefly model, optionally guided by a prompt.
    The workflow submits the generate-similar job, polls the status endpoint
    until the job reaches a terminal state, and branches on the result to return
    either the variation 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.
