GuestPaymentInformationManagementInterface

What it does

This interface defines the API contract for managing payment information and placing orders for guest (non-logged-in) customers during checkout.

Developers use this when building custom checkout flows or payment integrations that need to save payment details and place orders for guests, identified by cart ID and email address rather than customer ID.
