//! Post-export success modal.  Three buttons: OK (close), Open the
//! exported `<name>.toml` in the user's `$VISUAL` / `$EDITOR`, or
//! Open the surrounding config folder in the OS file manager.
//!
//! The theme has already been written and applied by
//! [`super::export_theme::ExportThemeModal`] before this modal opens, so all three
//! buttons are post-effect: dismissing is harmless.
