大桥坍塌动作序列

超写实电影级 15 秒动作序列。一辆汽车正全速行驶在长长的悬索桥上，身后桥体正在逐渐坍塌。 明亮的日光，缆绳断裂，桥段依次坠落。 动作保持持续向前。无急转弯。汽车保持直线行驶，路面逐段消失。 摄像机从低位前方开始追踪，以相等速度向后移动。仅有轻微的横向漂移。 序列中段，一大段桥面坠落，形成一个明显的缺口。 汽车加速并向前飞跃跨过缺口。 摄像机平滑地跟随弧线，保持与行进方向一致。 结尾处继续向前驶入剩余不稳定的桥跨。

Hyper-realistic cinematic 15s action sequence. A car is already at full speed racing across a long suspension bridge as it collapses progressively behind. Bright daylight, cables snapping, sections dropping in sequence. Action is continuous forward motion. No sharp turns. The car maintains a straight path as the road disappears segment by segment. Camera starts low front tracking, moving backward at equal speed. Slight lateral drift only. Mid-sequence, a large section drops, creating a clean gap. The car accelerates and jumps forward across it. Camera follows the arc smoothly, staying aligned with direction. End with forward motion into remaining unstable span.
