Make a pixel art sprite animation of a red panda mail carrier walking, side view. It must be real pixel art: a true 32x32 grid where every pixel is one solid square, no anti-aliasing, at most 8 colours, and a seamless 8-frame walk loop. If an image model is selected for this run, the art must come from it. Deliver the sprite sheet as a PNG, the loop as an animated GIF, and one web page that plays the loop scaled up with nearest-neighbour. It should feel alive the moment it loads.
