Seedance 2.0 Cavalry Charge Into Battle Cinematic Showcase Prompt

15-second extreme action war shot, one continuous impossible camera move. The camera starts inches above the dirt directly under a thundering cavalry charge, weaving between pounding hooves, flying mud, broken spears, and dragging banners. It glides impossibly low beneath horses without getting hit, then shoots through the center of an infantry collision, past shields slamming and swords flashing, before rising vertically up the shaft of a battle standard as if the flag itself were a tunnel. It bursts above the battlefield into a vast overhead reveal of the armies colliding below. Hyper-detailed dust, mud, cloth, and impact physics, impossible under-stampede camera path, epic historical-fantasy scale.
