Volcano Slope Rider Action Sequence

Hyper-realistic cinematic 15s action sequence. A rider descends a steep volcanic slope as lava advances behind. Heat distortion, glowing rock. Motion is gravity-driven downhill. No turning. Continuous seamless camera, aligned with slope direction. Start behind and slightly above, matching descent. Slide outward to a side angle, tracking parallel. Dip low near the ground, emphasizing speed. Rise again into a wider trailing angle showing lava behind. Mid-sequence, the ground drops sharply. Camera stays aligned, following the descent arc. Shift slightly forward-facing during the drop, then return to rear tracking on landing. End continuing downhill with a wider elevated angle.
