//! Small centered confirmation box for the autoreload watcher's
//! "file changed on disk — reload?" prompt ([`Prompt::FileReloadConfirm`]).
//!
//! Mirrors [`super::grammar_list::draw_grammar_install_prompt`]: a
//! message, a navigable Yes/No button pair (highlighting `accept`), and a
//! dim key hint. When the buffer had unsaved edits at detection time, an
//! extra warning line spells out that reloading replaces them (recoverable
//! with `u`). Key handling lives in the prompt layer.
