雨夜霓虹侦探（赛博朋克黑色电影）

Subject: a detective in his 40s in a long charcoal coat. Action: stands beneath a flickering neon sign in a rain-soaked alley, slowly lights a cigarette, looks toward the camera once, takes a drag, exhales. Scene: 1940s-meets-cyberpunk alley, wet cobblestones with neon reflections rippling at every step. Light: hard neon key in magenta and cyan, inky shadow fill, single overhead practical flickering. Camera: handheld eye-level medium close-up, slight breathing motion, no whip pan. Style: cinematic noir with cyberpunk grade, 21:9 anamorphic. Audio: rain on pavement, faint distant siren, the soft hiss of the burning cigarette. Constraints: face stable, no watermark, no text, no Logo on the signage, no extra limbs.
