 * Detects clicks outside of a specified element.
 *
 * @remarks
 * This hook returns a ref to attach to the element you want to monitor.
 * It subscribes to global pointer down events and checks if the click target is outside the ref element.
 *
 * @typeParam T - The HTML element type.
 * @param cb - The callback to execute when an outside click occurs.
 * @returns A ref object to attach to the target element.
 *
 * @example
 * ```tsx
 * const ref = useOutsideClick(() => {
 *   closeModal();
 * });
 * return <div ref={ref}>Modal Content</div>;
 * ```
