Rotate through the full panorama and inspect the left-right join. Look for lines, clouds, buildings or colors that jump at the seam. Compare the horizon in several directions instead of judging a single flat export. If the join distracts, adjust the prompt or regenerate before handoff; keep a copy of the original for comparison. A smooth seam supports immersion but does not by itself establish that every feature in the image is accurate.
