  Test game for campaigns. Three scenarios in a row. Each scenario starts the hero at 2 hp and the
  monster at 2 hp (not kept between scenarios, `reset`). Attack: a 1-in-2 chance to hit (monster
  -1), otherwise the hero loses 1 hp. A potion (+1 hp) costs 1 gold. Gold and scenarios won carry
  over (`persist: campaign`); each scenario won earns 1 gold. The trade-off: spend gold now or save
  it for a later scenario. Payoff = number of scenarios won.
