A full-screen preview of the fireworks screen effect in Apple Messages. When triggered, multiple vibrant firework bursts explode across the dark screen. The animation features realistic particle physics, where individual sparks shoot outward from a central point, decelerate, and cascade downwards due to simulated gravity while fading out. The haptic-aligned explosions stagger in timing, color, and position, creating an immersive and celebratory visual experience that fills the entire viewport behind the message controls.
