/**
 * Defines an element as a drop zone.

 * Drop zones respond to draggable elements being moved over them
 * by firing callbacks and applying CSS classes. They work with
 * the `draggable()` function from this module.
 *
 * @param el - The drop zone element
 * @param options - Configuration options
 * @returns A handle with a `destroy()` method
 *
 * @example
 * ```ts
 * import { droppable } from '@bquery/bquery/dnd';
 *
 * const handle = droppable(document.querySelector('#dropzone'), {
 *   accept: '.draggable-item',
 *   overClass: 'drop-active',
 *   onDrop: ({ dragged }) => {
 *     console.log('Dropped:', dragged);
 *   },
 * });
 *
 * // Later:
 * handle.destroy();
 * ```
