//! Auth helpers that are usable by both the CLI flow (`src/cli/auth.rs`) and
//! the in-TUI sign-in wizard. Keeps the device-code state machine free of
//! `println!`s so the TUI can drive it via channels.
//!
//! These helpers are deliberately additive: the existing `cli::auth::login`
//! is not refactored to use them (yet) to keep the change focused. A follow-up
//! can consolidate.
