- "an an app" -> "in an app" (content.py docstring)
- "wih" -> "with" (toast.md)
- "ot" -> "of" (styles.md)
- "wont" -> "won't" (reactivity.md, two occurrences)
- "progess" -> "progress" (progress_bar_isolated.py docstring)

 When a Textual app exits normally, the return code will be `0`. If there is an unhandled exception, Textual will set a return code of `1`.
 You may want to set a different value for the return code if there is error condition that you want to differentiate from an unhandled exception.
