A bright solid green screen background. In the exact center of the frame, a large number "3" stands still without moving. The number is surrounded by realistic burning fire effects, with flames flickering and flowing upward. The fire is dynamic and detailed, with glowing embers and small sparks occasionally drifting away. The number itself remains static and perfectly centered. No shadows, no extra objects, clean composition. Cinematic fire animation, high contrast, ultra realistic, 4K quality.
