2x2 Collage with Strict Identity and Pose Matching

A complex, structured JSON prompt for Gemini Nano Banana Pro designed for generating a 2x2 collage of a female subject, requiring strict preservation of facial identity, pose, camera angle, and expression based on an uploaded reference image. It details specific views (front, back, mirror selfie, side portrait) and environment settings (vintage-style indoor room) while locking the subject's identity and matching the reference image exactly.
