"""WalletPress Address Verification — BIP39/BIP32/BIP44 Compatibility Suite.

This is the trust foundation. Every address is verified against industry-
standard reference implementations (web3.py, nacl, coincurve).

PASS = your WalletPress addresses match MetaMask, Ledger, Phantom, etc.
FAIL = we have a bug. Fix before shipping.
