2x2身份鎖定拼貼

A highly structured JSON-based prompt for Nano Banana Pro to generate a 2x2 grid photo collage. It strictly locks the identity of the subject from an uploaded image while varying the setting, action, and outfit across four distinct panels (night outdoors, city street, mirror selfie, golden hour vehicle).
