 * WC_Order subclass for the email preview.
 *
 * The preview needs an order to render, but it must never read from or write
 * to a real order in the database. The key to that is the id: order methods
 * that touch the database key off get_id() and resolve to nothing when it is
 * 0 (add_order_note(), remove_order_items(), get_refunds(), the refund totals,
 * item/meta reads, etc.). So this order keeps id 0 and exposes the preview's
 * display number through get_order_number() instead.
 *
 * Two cases aren't safe at id 0 and are handled explicitly:
 * - save() and its siblings would insert a new row, so they are no-ops.
 * - get_customer_order_notes() passes the id to get_comments(), which treats
 *   0 as "no filter" and would return every order note on the site, so it is
 *   overridden to return nothing.
 *
 * The item/meta caches are pre-filled as empty too, as a guard against any
 * future read path that doesn't check the id first.
