//! The shell's "an AI assistant is in control" indicator, platform side.
//!
//! The control runtime decides when a session is running and what Stop does;
//! it sits above this crate, so it hands the Stop action down as a handler
//! and each desktop shell calls [`request_control_session_stop`] when the user
//! presses Stop.
