Should leave alt screen in panic hook

if let Err(err) = disable_raw_mode() {

Above this somewhere you should execute LeaveAlternateScreen to restore the buffer. Alternatively, define a struct that implements Drop to do that for you so you can bind it to a variable right after EnterAlternateScreen (or have it do both).

It’s a poor UX when TUIs don’t restore the user’s screen buffer, restore colors, etc.
