//! **CPU render-proof + state_json coverage for facett-search.** The inline tests
//! cover the `parse` grammar only; the `SearchBar::ui()` render path (the TextEdit +
//! the live "describe" summary label) and `state_json` are never exercised. This drives
//! a real `egui_kittest` frame so the widget paints, and asserts the parsed-query
//! summary rides into the AccessKit tree + is reflected in `state_json`.
