火山轨道骑行动作序列

超写实电影级序列。一名骑手正以极高速度沿着活跃火山区域上方的悬空工业轨道系统滑行。下方岩浆喷涌，空气中弥漫着火焰与灰烬。环境极不稳定：轨道扭曲、路段断裂、熔岩向上喷发，到处是热浪扭曲的视觉效果。动作节奏紧凑。骑手在轨道间滑行、跳跃，在路段崩塌的同时保持速度。镜头连续无缝。从火山熔岩区的广角镜头开始，随后俯冲向骑手。锁定轨道进行紧密跟拍。镜头在侧面掠过，升至上方展现断裂的线路，随后穿过火花与碎石降至轨道下方。序列中段，一次火山爆发摧毁了主要轨道。骑手穿过火焰与灰烬腾空而起，冲向另一条轨道。镜头拉远展现喷发全景，随后跟随骑手穿过碎石，在空中旋转，落地后重新锁定近距离追拍。结尾拉至广角：前方轨道断裂，下方岩浆肆虐。

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.
