• Sume reserves provider list times 1.25 at submit, so the price above is also the hold.

When the floor is the point

A floor-price clip is a motion check: does the prompt produce the move you described. It is not a statement about final quality, which you judge on your own frames. Keep the prompt and re-run it on a higher tier once it works.
