Grok Prompt: An ultra-realistic dirt bike rider racing forward with the camera tracking closely from the front. Dust and dirt kick up from the tires as the rider accelerates. The rider launches off a jump and performs a Superman-style trick, extending both legs straight back while holding the handlebars mid-air. Dynamic motion blur, frozen action at peak height, dramatic lighting, sharp detail on the rider and bike, cinematic angle, high-speed realism, intense energy.
