//! Terminal QR display and scanning for cold-wallet signing.
//!
//! Speaks the same wire protocol as the Quantus mobile app, the Quantus cold
//! wallet app and the Keystone firmware: payloads travel as `ur:quantus-sign-request`
//! URs (fountain-coded multi-part QR codes, encoded with the shared `quantus_ur`
//! crate), while cold-wallet addresses are plain SS58 strings in a single QR.
