No indoor smoking.

Generate exactly ONE 10-second vertical9:16 Omni1.1Flash video, 360p draft. Use v15-opening-start.png as the FIRST FRAME and v15-master-lit.png as the LAST FRAME. Preserve the identical set and stationary pair of slippers in both anchors. v15-master-lit.png is not an ingredient reference; it is the required end frame. Candid iPhone main 1x rear camera home VIDEO, not cinematic film or a polished commercial. Deep focus, ordinary slightly harsh Korean ceiling light when on, mild phone sensor noise in darkness, restrained phone sharpening and realistic skin. Subtle handheld breathing drift under 1% frame width, no gimbal push-in, no zoom, no new camera angle. The same stocky middle-aged Chinese man B, messy short black hair, ivory ribbed sleeveless undershirt, navy/red plaid shorts, always barefoot, never smoking. Same white wallpaper, wood doorway, wall switch, blue floral floor quilt, low table with red/cream/navy books. Same two grey cloth closed-toe open-back slippers, grounded beside quilt, ignored until the mosquito is discovered. No extra slippers. No insect flying or enlarging, no visible insect body in this clip. Keep all essential body parts, feet and prop interactions above 82% frame height and within the central86% width; bottom15% is disposable empty floor, not an added graphic border. Frame the existing scene wider if needed. Full frame9:16 without baked-in crop, no text/music/dialogue. Keep the room's architecture stable while the man moves.
At 0.00s he lies on his side beneath the quilt and the ceiling lamp is OFF. From 0.00s to 0.75s he irritably shifts his shoulders and rolls slightly, bothered by an offscreen mosquito sound to be added later; no hand swat. From 0.75s to 2.25s he pushes the quilt down and props himself up with his arms. At 2.25s he is sitting upright on the floor quilt. From 2.25s to 4.00s he plants his bare feet and stands up naturally without ever touching or wearing either slipper. At 4.00s he is fully standing barefoot. From 4.00s to 6.00s he takes two short barefoot steps toward the existing wall switch. From 6.00s to 6.75s he extends his right arm and touches the switch. At 6.75s he presses the switch once. From 6.75s to 7.00s the ceiling light switches on immediately after his press, with a brief realistic iPhone autoexposure adjustment, not a flash or gradual magical glow. From 7.00s to 8.75s he keeps his fingertip near the switch, squints angrily and turns his head back toward the room. From 8.75s to 10.00s he breathes naturally in the standing switch posture shown in the last frame, not yet pointing or approaching. End at 10.00s with the room light ON and the man upright on bare feet. Both slippers remain untouched in their original floor location and orientation the entire time. Do not turn on the light before the physical switch press. No sudden footwear or self-moving props. Keep the phone view continuous and low-amplitude, never reveal a second person or phone UI. The slippers are to the RIGHT of the quilt, close to its right edge. Nearest one is lower/left of its mate; both toes point diagonally toward the lower right. They never change floorboard coordinates or spacing. Any tiny phone drift affects the whole room together; it does not move props independently. Do not reinterpret floor props when the man stands up.
