Image Lab / concept rendering via the public API (async job + poll)

Our team has built an automated client-deliverable pipeline on the Handoff REST API. It uses POST /estimates with polling through /estimate-generations/{jobId}, POST /projects/with-estimate with a callback, catalog re-match, and file upload URLs. It works well end to end.

The one gap is Image Lab. It is UI-only on our tier, so a person has to run it by hand in the middle of an otherwise automated pipeline. We would like an endpoint where we POST a prompt, an anchor photo (file_id), and rendering constraints, and get back a rendered image through the same jobId and poll pattern the estimate generation uses.

We expect about 50-200 renderings a month, feeding an automated investment forecast deliverable for our buyer-side and seller-side clients.
