Strong rule: style --- 3D Pixar-style animation ---. A modern, bright office space with a large 'Doitong.com' logo on the wall. The AI robot floats in the center, gesturing toward a 'Start Free' button. In the background, people are working at sleek desks with views of a futuristic city. The lighting is clean, professional, and inviting.
Character appearance reference (MUST match exactly):
- AI Robot: A small, sleek, white-and-blue floating robot with large, glowing blue digital eyes that convey emotion. It has tiny wing-like appendages and a futuristic, polished metallic finish. The design is cute and high-tech, fitting a 3D animated world with soft neon glows and particle effects around it.
