常见问题
Why have separate shuffle and next actions?
Shuffle randomizes the whole queue once, then Next reveals picks one at a time — great for raffles or order reveals.
Can I undo a reveal?
Not yet. To start over, refresh the page and shuffle again.
Is the order truly random?
Yes. The queue is shuffled using the browser's Web Crypto API, so the reveal order is unbiased.
Does my list leave my device?
No. The picker runs entirely in your browser and works offline, so your list is never uploaded.
