Ultra-Photorealistic Bikini Portrait in Natural Light (JSON)

A highly detailed JSON prompt for generating an ultra-photorealistic portrait of a Chinese woman in a white bikini, sitting on a sun lounger in a private backyard patio. The prompt focuses heavily on natural light, realistic body physics (gravity on breasts, natural folds), skin texture (no airbrushing), and a casual, unposed posture, mimicking a raw iPhone photo.
