// Wallet lifecycle in the real browser: a LEGACY (ownerless) encrypted wallet
// with ownerless passkey/NWC/trust residue must migrate to the proven owner
// during password unlock - before the NWC service may start - and forgetting
// the wallet must drain/stop that service and remove every wallet-owned key
// before a successor wallet can be created without any of the old residue.
//
// The legacy encrypted record is produced here with the exact same KDF/wrap
// the app uses (keys.ts: PBKDF2-SHA256 210k -> AES-GCM), just without the
// owner marker a current build would stamp.
