Structured JSON Prompt for Luxury Couple Editorial Campaign

A highly constrained JSON prompt for generating an ultra-photorealistic luxury fashion editorial featuring a couple inside an art museum. It requires strict identity and pose matching to a reference image, specifies high-fashion wardrobe (strapless white mini dress, tailored black suit), and details the scene (seated on a gallery bench beneath a classical painting, reading abstract newspapers) with soft museum lighting for a sophisticated campaign look.
