}🟡create_letter(to, from, customer_email, idempotency_key, content, ...)
Create a printed letter order (up to 3 pages, 8.5x11, mailed in a #10 envelope) and get a payment link. Mails only after the user pays. Set certified to "certified" ($14.99) for USPS Certified Mail with tracking and proof of delivery, or "certified_return_receipt" ($19.99) to add the recipient's signature; use these when the user needs proof (landlord notices, legal or tax replies, disputes). Regular letters are $4.99.
