Strong rule: style --- 3D Pixar ---. An elderly Swiss man in his late 70s with a high forehead, thinning white hair combed back, and sharp, observant eyes behind round wire-rimmed spectacles. He wears a heavy brown tweed suit with a patterned waistcoat and a formal necktie. His expression is one of deep intellectual focus and calm wisdom. The background is a dimly lit 1920s library with rows of ancient books and a soft green glow from a desk lamp. The style is a realistic cinematic portrait with rich textures and dramatic chiaroscuro lighting, captured in a 16:9 landscape format.
