回溯2000年代：都市抓拍瞬间

Raw early-2000s flash-lit photo, vintage digicam aesthetic; man and woman (keep original faces from both uploaded photos exactly, do not alter facial features in any way, no face changes even 1%) standing back to back on a sidewalk near a street corner; outfits: layered casual looks denim jacket over white tank on her, dark jacket over ribbed tank on him; pose: bodies touching lightly at the back, hands hanging loosely, heads turned slightly away from camera; expression: serious, reserved, emotionally closed; lighting: aggressive direct flash flattening the scene, strong contrast between subjects and background; background: crosswalk, street sign, faded storefronts; composition: waist-up framing, awkward crop, candid street-photo energy; visible skin texture, natural pores, harsh flash emphasizing imperfections; grain, digital artifacts, early-2000s snapshot realism.
