/// etui, TUI library for Gleam.
///
/// Correct Unicode, minimal diff, no terminal left broken.

/// ## Quick start
///
/// ```gleam
/// import etui/app
/// import etui/backend
/// import etui/backend/default
/// import etui/buffer
/// import etui/geometry.{rect_new}
///
/// pub fn main() {
///   let _ = app.run_buffered(
///     default.new(),
///     Nil,
///     fn(_state, screen) { buffer.buffer_new(screen) },
///     fn(ev, state) { case ev { backend.KeyPress("q") -> state _ -> state } },
///     fn(_) { False },
///     16,
///   )
