ORIGINAL UNTESTED EXPERIMENT PLAN

Positive prompt: One blue lantern stands on the right of a pale wooden tabletop. Curved handle, amber chamber, blue side rails and coral base knob fully visible. Quiet warm neutral area on the left for later copy. Soft side light and clear contact shadow. Complete object, no lettering.

Optional exclusion candidate in a supported Base negative-prompt field: additional lanterns, lettering, decorative border.

Record checkpoint/revision, implementation/version, canvas, seed and all sampling settings. Inspect one baseline output. Name the actual failure. Change one meaningful variable. Compare the requested improvement and any new regression. Save the accepted candidate separately. This is not a completed model run, hard billing cap or guarantee of reproducibility across implementations.
