  Two-stage model. Stage 1: an API Key + API Secret (HTTP Basic, Base64(API_KEY:API_SECRET))
  authenticates the /api/pay1st/auth/token call to mint a short-lived Access Token plus a
  Refresh Token. Stage 2: every other Gateway request carries the Access Token in the
  AccessToken header as "Bearer <AccessToken>", and every mutating request is additionally
  signed with a hex HMAC-SHA256 X-SIGNATURE (over X-TIMESTAMP + request JSON, keyed by the
  Signing Key) to prove the payload was not tampered with. Credentials are generated in the
  Pay1st Console.
