涩谷跑酷一镜到底（多音轨）

Single continuous cinematic shot in Shibuya. Subject: a Japanese schoolgirl in uniform, hair tied back. Action: she sprints at extreme speed, weaves along crosswalks, runs along low walls, leaps, rolls on landing, dashes forward again. Scene: Shibuya scramble crossing at dusk, neon signs above, busy crowd. Light: warm sunset key plus emerging neon practicals, motivated. Camera: low and close to the ground, following every leap and roll; gimbal stabilized, no whip pans. Style: photoreal urban parkour cinematic. Audio mix: daytime street noise, retro 8-bit game sounds layered on jumps, shamisen plucks accenting beats. Constraints: maintain face stable, no watermark, no on-screen text, no doubles.
