Useful answers
Is every selected group guaranteed?
Yes. Rejection sampling produces uniform candidates and discards those missing a selected group. Passwords are never stored.
What are the limits?
QR content is limited to 1500 bytes and may require a larger output size. Password length: 8–128 characters. UUID batches: 1–1000. Modern browsers with Web Crypto are required.
