🆕 B20 Stablecoin tokens self-declare a fiat currency code (currency() → USD, EUR, …). Reads that declared peg alongside the issuance profile (supply, cap) and control powers (seize/freeze/pause/uncapped-mint) — a one-call 'what is this stablecoin and who controls it' for agents settling in B20 stablecoins. The currency code is the issuer's claim, not attested backing.
