//! #20 Pattern B — the confirm-before-destroy modal. Small,
//! centered dialog with a title / message / [Cancel] / [Confirm]
//! button row. Default focus lands on Cancel (safer default);
//! Y/y fires Confirm, N/n / Esc / Cancel dismisses.
//!
//! Owned by `App.pending_confirm: Option<PendingConfirm>`. When
//! set, this module paints on top of everything and the tui
//! input loop routes all keys / mouse to `commit_pending_confirm`
//! / `dismiss_pending_confirm`.
