Verifies the recipient and sender addresses and locks a 15-minute USDC price for mailing a postcard built from two postcard_art documents (front + back, uploaded via create_postcard_art). Sizes: 4x6 (default), 6x9, 6x11 — postcards always print in full color. US recipients use the strict US address shape; INTERNATIONAL recipients are supported on 4x6 only (set `to.country` to the 2-letter ISO code; the sender must still be a US address). Payment works exactly like letters: pay the returned `paymentUrl` via x402, or use the MPP/checkout fallbacks. Show the recipient, sender, size, selected-route `design` constraints, price, AND any `fulfillment.warnings` to the user and get explicit confirmation before paying — service level is a soft preference and may have been downgraded (e.g. international economy is upgraded to standard) with a `service_level_downgraded` warning the agent must surface verbatim.
