冷色灯光，近距离的一段即兴。

Create a 15-second solo cold-room rap. Image 1 defines the lead; preserve face, hair and build. Dark blue loose zip hoodie, light shirt, simple chain and watch. A white walk-in cold room has metal shelves stacked with plain white boxes, overhead cooling equipment and cold lights with a slight cyan-green cast. No readable labels. Start beside a white wall, rapping to the lens and swaying, then approach and point one finger toward the camera to accent a line. In the middle, turn and move alongside the shelves, glance at the boxes and gesture toward them. Face the camera again, alternating downward presses and forward hand pushes to the beat. Toward the end, lift a fist beside the temple, dip the head on a beat, turn toward the shelves and look back while rapping. Landscape handheld medium and medium-close shots; slowly approach, move sideways and back away in the same room. Continuous rhythmic mouths, natural hands, stable identity, hoodie, boxes and lighting. Original rap vocals, deep bass and spare drums; no source song, artist voice, footage, subtitles or watermark.
