Animate the miniature city model while preserving the exact original design, geometry, proportion...

Animate the miniature city model while preserving the exact original design, geometry, proportions, colors, material, camera angle, framing, lighting, and background. The entire city model rotates smoothly around its central vertical axis, completing exactly one full 360-degree rotation. The rotation must be continuous and at a constant, perfectly even speed from beginning to end, with no acceleration, deceleration, pauses, or changes in direction. At the same time, add tiny stylized cars driving along the existing roads of the city. The cars should follow the road paths naturally and continuously, maintaining their lanes and moving at a small, steady speed. Add tiny stylized people walking along the streets and sidewalks, moving naturally through the miniature city. The cars and people must have exactly the same bright green material, color, smooth rounded geometry, and slightly toy-like appearance as the city itself. They should look like miniature elements that were physically molded from the same material as the city, not realistic humans or realistic cars. Keep the animation subtle, clean, charming and playful. The city rotation is the main motion, while the cars and pedestrians provide secondary life and activity. Do not change, add, remove, deform, or redesign any existing buildings, roads, trees, or other elements. Do not change the camera position or perspective. No camera movement, no zoom, no parallax changes. The composition and original appearance must remain completely consistent throughout the animation.
