abstracttui 0.2.19

//! Component model: declarative view tree, mounting, event routing
//! (capture -> target -> bubble), hit testing, focus management, keymaps
//! and shortcuts. Components are plain functions over reactive scopes
//! returning `View` blueprints; re-render is driven by signals, scoped
//! to the `Dyn` region that read them.
//!
//! Owner: REACT. Contract notes live on the types; the architectural
//! rationale is in `docs/design/reactive-ui.md`.
//!
//! ## Component pattern
//!
//! ```ignore
//! fn counter(cx: Scope, start: i64) -> View {
//!     let count = cx.signal(start);
//!     Element::new()
//!         .style(Style::row().gap(1))
//!         .focusable()
//!         .on_event(move |_ctx, ev| {
//!             if let UiEvent::Key(k) = ev {
//!                 if k.key == Key::Char('+') { count.update(|c| *c += 1); }
//!             }
//!         })
//!         .child(dyn_view(Style::default(), move || text(format!("count: {}", count.get()))))
//!         .build()
//! }
//! ```
