#![allow(dead_code)] // Phase 1: methods consumed as screens are implemented

//! Full FrankenTUI Model implementation for the lore TUI.
//!
//! LoreApp is the central coordinator: it owns all state, dispatches
//! messages through a 5-stage key pipeline, records crash context
//! breadcrumbs, manages async tasks via the supervisor, and routes
//! view() to per-screen render functions.
