until user interacts (before bootstrap completes a game)
- clicking New Game on overlay clears history and starts fresh (0 moves)
- clicking Resume restores saved move history length exactly
- HUD new-game button resets history to 0 and score to 0
- tab-visibility timer: timer freezes during hidden, resumes when visible
