Unscrewing a water bottle cap

Single continuous handheld smartphone-style shot, vertical 9:16 framing. A matte black stainless-steel water bottle with no label and no logo stands on a light wooden kitchen counter beside a sunlit window. A single hand grips the cap and twists it counterclockwise until it lifts free of the standing bottle, then sets the cap down on the counter beside it with a soft tap, and the hand withdraws. The camera is held at eye level in a medium close-up with a slight natural handheld sway and one small steady push-in toward the bottle, with no cuts. Natural window light from the left, soft shadows, slightly imperfect exposure like a real phone video, shallow depth of field with a blurred green plant in the background. The bottle stays in the central band of the frame, and the top tenth and bottom sixth remain calm counter and background. Sound design: quiet kitchen room tone, the soft click of the cap turning, a gentle tap when it is set down, no music, no voice. No text, no logos, no watermark, no faces.
