The undo/redo confirmation dialog capped at 60 columns and wrapped even a short insert on wide terminals, showed a lowercase "snapshot taken", a raw ISO-8601 timestamp, and lowercase yes/no labels. Grow the dialog to fit its longest line (bounded 34–100), capitalise Snapshot/Yes/No, and render the snapshot timestamp in local time, human-formatted (24 May 2026, 11:00) via a new chrono dependency (clock feature only; English month names). Yes/No capitalisation also applies to the rebuild-confirm dialog.
