K-Pop Idol Portrait Grid for Rapid Selection

A detailed JSON-structured prompt for Nano Banana Pro designed to rapidly generate nine variations of a K-Pop idol portrait based on an input photo. The prompt specifies the subject's demographics, fashion, pose, a nighttime park environment, and technical camera settings (3:4 aspect ratio, warm street lighting, shallow depth of field) to create a 'boyfriend material' aesthetic. The output is arranged in a 3x3 grid with numbered options for quick selection and high-resolution output of the chosen image.
