//! `tuika` — a small retained-tree terminal UI toolkit over
//! [`ratatui`](https://docs.rs/ratatui).
//!
//! `tuika` adds the pieces ratatui leaves to you — a flexbox-style layout
//! solver, anchored overlays, focus/input-ownership, an alternate-screen host,
//! and a set of components (text, boxes, scroll, select, spinner, progress) —
//! while letting ratatui keep ownership of the cell buffer and its diff against
//! the terminal. It depends only on `ratatui`, `crossterm`, `textwrap`, and
//! `unicode-width`.
//!
//! It was extracted from the [yolop](https://github.com/everruns/yolop) coding
//! agent, whose full-screen renderer is built on it, but it knows nothing about
//! any host application.
//!
//! # Model
//!
//! - **Views** ([`view::View`]) are ephemeral, rebuilt from application state
//!   each frame; ratatui diffs the resulting cell buffer, so this is cheap.
//! - **State** that must persist across frames ([`components::ScrollState`],
//!   [`components::SelectState`], [`focus::FocusRegistry`]) lives in the host,
//!   in the `StatefulWidget` idiom.
//! - **Layout** is a flexbox subset ([`layout`]); **overlays** ([`overlay`])
//!   anchor over the base tree; the **host** ([`host`]) owns the alternate
//!   screen, translates crossterm input, and composites the frame.
//!
//! # Extending
//!
//! Add a component by implementing [`view::View`] in a new module under
//! [`components`]. No registration step; containers accept any boxed `View`.
