About the Random Number Generator
Set a minimum and maximum, choose how many numbers you want, and decide whether duplicates are allowed. Turning duplicates off gives you a fair draw for raffles, team selection or lottery-style picks.
Numbers come from the browser's cryptographic random source rather than a predictable pseudo-random sequence, and you can keep a history of previous draws for transparency.
