 * wallet method (batch `signPsbts` is optional), so single-sign is the portable
 * choice — some integrations (notably MPC / institutional wallets) prefer it.
 * For a real batch (>1), wallets exposing native `signPsbts` (e.g. UniSat) sign
 * in one interaction; others loop `signPsbt`.
 *
 * @throws If native `signPsbts` returns a different number of signed PSBTs
 *         than were submitted.
