Art style: 3D Medical Illustration.
A clinical educational split card inside a calm exam-room setting with a muted wall chart, bedside table, and neatly arranged sleep diagram materials in the background. Left panel shows a bed with stacked pillows bending the neck forward; right panel shows the whole bed frame gently tilted upward at the head with a straight neck line highlighted. Eye-level medium-wide composition, symmetrical comparison layout. Soft diffused medical-office lighting, neutral and trustworthy mood, clear corrective atmosphere. Dominant palette: white, slate blue, muted gray, soft teal, pale beige.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Medical Illustration" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Medical Illustration". 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 "3D Medical Illustration" idiom, not in any other medium.
