The two framework-free 0%-coverage modules: the recent-files list (dedupe by name, eight-entry cap, corrupt-localStorage tolerance) and the labelled undo/redo mirror against a live jsdom editor (labels per edit kind, undo/redo moves, redo branch discarded by a fresh edit).

// The recent-files list (storage/recentFiles.ts): dedupe by name, newest first,
|
|
// capped at eight, and tolerant of corrupt localStorage. jsdom has no IndexedDB,
|
|
// so the handle side no-ops — exactly the browser-without-picker path.
