Hyper-realistic portrait on a yacht at twilight

An extremely detailed, photorealistic prompt for Nano Banana Pro focusing on a young Caucasian woman on a yacht deck at twilight. The prompt includes explicit details about her physical features, clothing (ruched mini-dress), pose (emphasizing cleavage and natural volume), environment (ocean, stainless steel railings), and lighting (soft, diffused evening ambient light) to achieve high anatomical fidelity and realism.
