/**

 * Plugin Name: POP Cats – Hide Bundle Containers from Legacy REST API

 * Description: Removes WooCommerce Product Bundles container line items from

 *              Legacy REST API (v3) order responses so the AMSCO/ShipHero

 *              integration imports only the pickable child items.

 *              The modern REST API (/wp-json/) used by Shippo, Zoho, etc.

 *              is completely untouched — this hook only exists in the

 *              Legacy API request lifecycle.

 * Author:      POP Cats

 * Version:     1.0.0
