        )}

Performance Tips

Use layoutId for shared element transitions
Use useReducedMotion() to respect user preferences
Avoid animating layout properties (width, height) - use transforms
Use will-change sparingly via Tailwind's will-change-transform
Prefer opacity and transform animations (GPU accelerated)
