Prompt

Maintain the exact illustrative style and colors of the 1976 flag stamp. Animate only the elements found on the stamp: the blue Kansas state flag billows forcefully, with folds rolling like ocean waves. Within the tiny state seal, the miniature steamboat chugs across the river, and the rising sun pulses. The bright yellow sunflower atop the seal twirls playfully like a golden top. Do not add any new elements.
