3/// A trait for widgets that have a fixed size.
4///
5/// This trait allows the popup to automatically size itself based on the size of the body widget.
6/// Implementing this trait for a widget allows it to be used as the body of a popup. You can also
7/// wrap existing widgets in a newtype and implement this trait for the newtype to use them as the
8/// body of a popup.
9///
10/// This trait was previously called `SizedWidgetRef`, but was renamed to [`KnownSize`] to avoid
11/// confusion with the `WidgetRef` trait from `ratatui`.
