the llm produced something the operator thought was garbage for the design too, and the operator iterated it from garbage to good.
they could also have the llm iterate the underlying code from garbage to good, if they wanted.
most likely a specialist would say its neither good nor bad, since its not considering the right things, and hasnt collected the right useability feedback, but making straightforward designs isnt that hard, and counting clicks and interactions, and avoiding hidden functionality is all measureable stuff
