//! Activity-bar keyboard navigation demo — TUI backend.
//!
//! Demonstrates [`quadraui::ActivityBar::is_keyboard_focused`]: the backend
//! emits `UiEvent::ActivityBar(id, ActivityBarEvent::KeyPressed { … })`
//! instead of a raw `UiEvent::KeyPressed` when a bar declares keyboard focus,
//! so navigation logic stays entirely in app code.
//!
//! Controls:
//! - **Tab** → focus the activity bar (cursor appears on first item)
//! - **j** / **↓** → move cursor down
//! - **k** / **↑** → move cursor up
//! - **l** / **Enter**→ activate highlighted item, return focus
//! - **Esc** / **h** → return focus without activating
//! - **q** / **Esc** (editor area) → quit
//!
//! ```sh
//! cargo run --example tui_activity_nav --features tui
//! ```
