When you iterate on an AI-generated image by re-prompting, you destroy it.
You ask the model to "move the figure left and remove the truck," and the entire scene shifts: different lighting, different building geometry, different snow texture. Anything that wasn't pinned by the original seed gets re-rolled. You lose the bake you liked.
Photographers don't work this way. Concept artists don't work this way. They hold the layers and move them.
I wanted that. So I built it.
