The shippable version. Cut the subject out once, then drop it onto any backdrop — a clean studio white for product shots, a brand colour for consistency, or a gradient for a profile picture. Every option is composed on a canvas in the browser; the photo never leaves the tab.
Swapping backdrops is instant because the model runs only once — the matte is reused and only the canvas composite changes. That's the pattern for a real product pipeline: segment once, re-skin many times.
