1//! Terminal UI for real-time process monitoring.
2//!
3//! The TUI connects to a running daemon session and displays a split-pane
4//! layout: a process list on the left and streaming output on the right.
5//! It polls status every 2 seconds and streams output via `Logs --follow`.
6//!
7//! See [`app`] for state management, [`input`] for keybindings, and
8//! [`ui`] for rendering.
