Create a pre-checkout cart from catalog line items. A cart is a mutable scratchpad: it moves no money and holds no inventory, so it carries estimated (server-derived) totals and NO payment_handlers. Assemble it, then create_checkout(cart_id) to convert. REQUIRES IDENTITY on a signature-required Terminal.
Input schema
