Hyper-realistic cinematic sequence. A rider grinds at extreme speed along a suspended industrial rail system above an active volcanic field. Lava erupts below, fire and ash filling the air. Environment is unstable: rails twisting, segments breaking, molten bursts erupting upward, heat distortion everywhere. Action is immediate. The rider grinds, jumps between rails, maintaining speed while sections collapse. Continuous seamless camera. Start wide over lava fields, then dive toward the rider. Lock into tight tracking along the rail. Whip alongside, rise overhead to reveal broken lines, drop under rails through sparks and debris. Mid-sequence, a volcanic blast destroys a major rail section. The rider launches through fire and ash, aiming for a secondary rail. Camera pulls wide to show eruption, then dives with the rider through debris, rotating mid-air, locking back into close pursuit on landing. End wide: fractured rails ahead, lava chaos below.
