Browser Randomness Note

This tool generates numbers in your browser. For stronger browser-based randomness, modern JavaScript can use crypto.getRandomValues() instead of only basic Math.random(). This is helpful for better random number distribution, but the tool should still be used for general-purpose random selection, not certified lottery, gambling, legal, or cryptographic security use.
