// - Runner window: only one UI (no duplicate texts)
// - When parent closes, runner keeps polling localStorage (timers/settings) every 1s
// - name 유지 + runner-status: "다음 알람: {name} · {remain} 남음"
// - Modal overlay center (no layout shift) + dim background
// - Icon toggle + X(danger) close + overlay click close
// - Style included (Bootstrap theme friendly: uses CSS variables)
