This component respects the prefers-reduced-motion media query via useReducedMotion from Motion. When reduced motion is preferred, the magnetic cursor-following effect is completely disabled. The component also detects hover-capable devices and disables the effect on touch devices. When the disabled prop is set, the magnetic effect is also disabled.
