Memento-based undo/redo with full encounter snapshots. Undo stack capped at 50 entries, persisted to localStorage. Triggered via buttons in the top bar (inboard of turn navigation) and keyboard shortcuts (Ctrl+Z / Ctrl+Shift+Z, Cmd on Mac, case-insensitive key matching). Clear encounter resets both stacks.
