//! Interactive terminal UI — entry point and event loop.
//!
//! Architecture (borrowed from cc-switch-cli):
//! - `app/`  — App state, overlay enum, event cascade, action handler
//! - `ui/`   — pure rendering: chrome (header), content tabs, overlays, footer
//! - `theme` — colors + no_color accessibility mode
//!
//! Input priority cascade: overlay → globals → tab content. An active overlay
//! suppresses all other keys, so vim motions inside a log viewer never leak
//! into tab switching.
