Art style: Cinematic Realistic.
Vertical 9:16. Cinematic visualization of the human biological clock. A realistic sleeping person appears in the center while a luminous circular clock mechanism surrounds the body. Multiple subtle time markers repeat around the circle, representing the same wake-up time on different days. The person's brain emits a gentle synchronized pulse with the biological clock. Dark blue environment with warm golden highlights, realistic human anatomy, sophisticated scientific visualization, volumetric lighting, high detail, Unreal Engine 5, Netflix science documentary quality.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
