Create a photorealistic image of a chubby, adorable white cat athlete performing a somersault on the horizontal bar during the Olympic gymnastics finals. The cat should be captured mid-air, executing the somersault with skill and grace. The background features a grand Olympic stage with bright lights and an enthusiastic, cheering crowd. The image should highlight the cat’s fluffy fur, the dynamic action of the somersault, and the excitement of the moment amid the roaring spectators. --ar 1:1 --niji 6
