Struct ScreenOptionsDialog 

pub struct ScreenOptionsDialog { /* private fields */ }

Screen-options dialog.

Holds a snapshot of the initial ModalStyle and a mutable pending copy that tracks the user’s radio selection. Emits DialogAction::ApplyModalStyleLive on F2 / Enter on [Apply live], DialogAction::ApplyModalStyleAndSave on F10 / Enter on [Apply + Save], and DialogOutcome::Close on Esc / Enter on [Cancel]. Pressing Enter on a radio row sets pending to that option without moving the cursor.
