1//! Improv desktop GUI (`improv-gui`) — Phase 5.
2//!
3//! An `egui`/`eframe` front-end: a *view* over the engine (see
4//! `.agent/steering/AGENT_GUI_STEERING.md` §9). It loads a model from a store
5//! (a Mentat file or a `postgres://…?model=` URL), renders a measure as a pivot grid, and (Phase 5 increments) offers a
6//! model browser, formula editor, and Info panel.
