/**
 * Global trackpad detector instance for wheel events.
 *
 * Use this pre-configured detector to check if a wheel event originated from a trackpad
 * rather than a traditional mouse wheel. The detector maintains state across calls to provide
 * consistent results throughout a scroll session.
 *
 * @example
 * ```typescript
 * import { isTrackpadWheelEvent } from './utils/functions';
 *
 * canvas.addEventListener('wheel', (event) => {
 *   if (isTrackpadWheelEvent(event)) {
 *     // Handle smooth trackpad scrolling
 *     applyMomentumScrolling(event);
 *   } else {
 *     // Handle discrete mouse wheel steps
 *     applySteppedScrolling(event);
 *   }
 * });
 * ```
