Luxury Low-Light Fashion Portrait Prompt with Strict Identity Lock in JSON

A highly structured JSON prompt for Nano Banana Pro designed to generate a 3/4 body fashion portrait in a dim luxury hallway. The prompt enforces 100% facial identity consistency based on a reference photo and details complex attire (strapless top, low-rise briefs, body chains, sheer patterned tights, and an oversized fur coat) using cinematic low-light realism.
