 * `X402Signer` (recipient check / per-call cap / session budget /
 * SigningPolicy). This module retains only protocol-shape helpers that have

 *
 * - `EIP3009_TYPES` — the EIP-712 type definition for
 *   `TransferWithAuthorization` (consumed by the buyer when building the
 *   payload it hands to `X402Signer.signPayment`). NOTE: distinct from the
 *   SDK's `EIP3009_TYPES` (a Set of primary-type NAMES for its
 *   SigningPolicy) — this is the full types dict.
 * - `buildXPaymentHeader` — encodes the x402 v2 envelope as a base64 header.
