4/// Errors produced by the TUI subsystem.
5///
6/// All variants implement [`std::error::Error`] via [`thiserror`] and carry a
7/// source error for full cause chains.

9/// # Examples
10///
11/// ```rust
12/// use zeph_tui::TuiError;
13///
14/// fn check(e: &TuiError) -> bool {
15///     matches!(e, TuiError::Io(_))
16/// }
17///
18/// let io_err = std::io::Error::other("disk full");
19/// let tui_err = TuiError::from(io_err);
20/// assert!(check(&tui_err));
21/// ```
