Does the countdown stay accurate in a background tab?
Yes. The timer recalculates from the real clock, so it stays accurate even if you switch tabs.
What happens if I refresh the page?
The countdown resets — the target is not stored in the browser.
Can I set a target in the past?
Yes — the countdown then finishes immediately and shows Time's up!
