Cinematic Mirror Selfie: Batman and Catwoman Cosplay

A highly constrained JSON prompt for Nano Banana Pro to generate a photorealistic mirror selfie of a couple cosplaying as Batman and Catwoman inside a modern elevator. It requires two reference images for strict identity lock and specifies detailed wardrobe (bat-cowl, cat mask, yellow bat emblem) and environment (stainless steel elevator, cool ceiling lights) to ensure accurate reflections and cinematic contrast.
