Underwater Floating Door Scene

Generate a photorealistic full-body underwater photograph of a person in dark, loose clothing floating horizontally beneath the surface, their spine parallel to the frame's bottom edge, head to the left and feet to the right. The person's arms are relaxed with open palms, knees loosely bent, face tilted upward toward the surface with a gentle gaze, and fine bubbles rising diagonally from their body toward the upper portion of the frame. A whitish four-panel door floats horizontally in the upper third of the image, centered and positioned just below the rippling water surface, its bottom side visible with four legible embedded rectangles and a small dark knob near the lower middle edge, with silver foam and reflections gathered just above it. The water forms a deep gradient from cobalt blue near the surface to nearly black at the bottom, creating considerable negative space around the subject. Lighting comes only from above with soft volumetric rays and crisp highlights on the lower portion of the door, minimal backscatter, sharp detail in the bubbles and clean edges throughout. The color palette features cinematic bluish-teal tones with neutral whites. No fish, particles, text, or additional elements.
