product-image: a set of product images to choose between

"Four main images in different styles" is a set, and a set is a different job from one picture. It has a shape nobody asked about out loud — how many, varying what, and does the product stay the same across them — and it has a price that is the total, not the per-image figure.

This skill is a thin, scenario-specific layer over ofox-image-core. It owns the set's composition, the per-style prompt craft, the consistency requirement and the set-total pricing; ofox-image-core owns talking to the Ofox image API correctly and safely — the OFOX_API_KEY handling, model resolution, requests, decoding, cost arithmetic and absolute paths. Read that skill's safety contract before using this one — it is not restated here.
