/**
 * The [DeleteBox](https://engine.needle.tools/docs/api/DeleteBox) component creates an invisible deletion zone that destroys objects entering it.
 * Works with objects that have a {@link Deletable} component attached.
 *
 * ![](https://cloud.needle.tools/-/media/J-Gmdhl214kfdjkfYViG8g.gif)
 *
 * **Use cases:**
 * - Trash bins in sandbox builders
 * - Kill zones in physics simulations
 * - Cleanup areas for multiplayer scenes
 *
 * **Setup:**
 * 1. Add DeleteBox to a GameObject with a BoxCollider-like shape
 * 2. Add {@link Deletable} component to objects that should be destroyable
 * 3. Objects entering the box will be destroyed (synced across network)
 *
 * **Debug:** Use `?debugdeletable` URL parameter to visualize deletion areas.
 *
 * - Example: https://engine.needle.tools/samples/collaborative-sandbox
 *
 * @example Create a deletion zone
 * ```ts
 * const trashBin = trashBinModel.addComponent(DeleteBox);
 * // Objects with Deletable component will be destroyed when entering
 * ```
 *
 * @summary Box area that deletes objects entering it
 * @category Interactivity
 * @group Components
 * @see {@link Deletable} - Add to objects that can be destroyed
 * @see {@link Duplicatable} for spawning objects
 * @see {@link DragControls} for moving objects
