//! Shared authentication leases for interactive frontends.
//!
//! A session owns its secret store, so callers cannot bypass a lease by retaining
//! an independently unlocked store. Frontends explicitly report real user input
//! with [`AuthenticationHandle::touch_user_activity`]; secret reads, Git work,
//! refreshes, timers, and repaints deliberately do not extend the deadline.
