//! A minimal example of a Ratatui application.
//!
//! This is a bare minimum example. There are many approaches to running an application loop,
//! so this is not meant to be prescriptive. See the [examples] folder for more complete
//! examples. In particular, the [hello-world] example is a good starting point.
//!
//! This example runs with the Ratatui library code in the branch that you are currently
//! reading. See the [`latest`] branch for the code which works with the most recent Ratatui
//! release.
