Types the spec asks for beyond the payment card itself: settlement
account (20 digits), BIK, card expiry date (kept separate from
birth date), OGRN/OGRNIP (negative lookahead so OGRNIP isn't half-
swallowed by the OGRN rule), KPP, income/salary amounts, and mentions
of biometric enrollment (ЕБС, voice/fingerprint templates).
