Cinematic live-action, 16:9, 24fps, 30 seconds. Gritty concrete emergency stairwell, floor "28" sign on the wall, cold desaturated grey-green color grade, harsh overhead fluorescent tube lights, shallow depth of field, subtle film grain. A young Korean woman in a champagne satin sleeveless blouse, black leather mini skirt, sheer black tights, thin wire-rim glasses, hair in a sleek low bun, clutching a manila folder. She presses against the wall, breathing nervously, as a group of men in white dress shirts and ties descend the stairs toward her. Shot 1: Extreme close-up, her glasses reflecting light, eyes darting, fearful. Slow push-in. Shot 2: Her expression shifts from fear to cold focus; she drops the folder, clenches her fist. Papers burst into the air. Shot 3: Wide low-angle, she explodes into action: a high spinning kick sends the first man flying into the door. Shot 4: Side tracking shot, slow-motion roundhouse kick against the railing, papers floating mid-air. Shot 5: Fast hand-to-hand choreography, cuts timed to the impacts, camera shake on hits. Shot 6: Final kick, dust and debris explode off the wall, the last man slumps down. Shot 7: Rear wide shot, she stands calmly amid the scattered papers and straightens her blouse. Style: John Wick-style stair fight, realistic physics, dramatic slow-motion on key kicks, deep bass hits, ambient reverb, paper rustle and impact sound design. Negative: no text overlays, no distorted faces, no extra limbs, no cartoon look.
