都市跑酷夜行（FPV 无人机） prompt

Scene: A narrow urban alley at night, magenta and cyan signage spilling onto wet asphalt, scaffolding overhead. Characters: A parkour runner in black sportswear, hood up. Action: The runner sprints into frame, vaults a row of dumpsters in one fluid motion, slides under low scaffolding without breaking stride, drags one gloved hand along a metal railing — sparks erupt and trail behind him. He launches off a stair edge and the camera barely keeps pace. Camera: Dynamic FPV drone shot, low and fast, chasing tightly behind the runner with quick yaw corrections through obstacles. Audio & Style: Breath rhythm in close mic, footfalls slapping wet ground, distant city hum, gritty handheld grade.
Negative: slow motion (unless cued), sliding feet, floating limbs, watermark.
