幽默自拍

A complex JSON prompt for Nano Banana Pro to generate an ultra-photorealistic, behind-the-scenes (BTS) selfie featuring three specific characters (main reference, Rachel, and Chandler) on a 90s sitcom soundstage. It enforces strict identity lock for all subjects and includes detailed constraints for the holiday setting (Santa hats, themed tree) and technical camera details (ARRI ALEXA Mini LF style) to simulate a high-quality production photo.
