/**
 * Daily Disruptions and Random Events
 *
 * Random disruptions that make daily life feel varied (1-2 per week).
 * Each has real gameplay tradeoffs affecting time, money, or stats.
 *
 * Events:
 * - carWontStart: Car trouble, repair choice (money vs time)
 * - foundMoneyOnGround: Lucky find (small money gain)
 * - surpriseVisitor: Unexpected guest (energy vs social)
 * - doctorAppointment: Mandatory health check (time cost, health benefit)
 * - snowDay: School/work cancelled (happiness boost, schedule disruption)
 * - powerOutage: No electricity (productivity loss, boredom)
 * - flatTire: Tire blowout (money or energy cost)
 *
 * Sleep quality events:
 * - nightmareEvent: Bad dreams from low happiness
 * - greatSleepEvent: Restful sleep from exercise
 * - insomniaEvent: Can't sleep with high energy at bedtime
