9 格身份固定肖像

A complex JSON-formatted prompt designed for Nano Banana Pro to generate a 3x3 grid collage of a person, showcasing 9 different expressions, hairstyles, outfits, and backgrounds while strictly maintaining the exact facial identity and bone structure across all panels. This is ideal for creating consistent character sheets or high-quality, varied portraits from a single reference image.
