Riverflow 2 Pro API — previous-generation Sourceful flagship

Riverflow 2 Pro is the earlier flagship of Sourceful's image line, still favored for detail-heavy product and packaging renders.

YepAPI keeps it callable on `/v1/media/queue` at about $0.70 per image so existing pipelines keep running while you evaluate Riverflow 2.5.
