Grok Prompt: An ultra-realistic skier speeding downhill with the camera tracking alongside. Snow sprays from the skis as the skier approaches a jump. The skier launches into the air and performs a clean backflip, fully inverted at peak height, then prepares to land smoothly. Crisp alpine lighting, frozen mid-air action, detailed snow particles, sharp focus on the skier, cinematic motion, high-speed realism, intense but controlled energy.
