Fun Facts

The Web Crypto API provides cryptographically secure random number generation directly in the browser — no server round-trip needed.
The Mersenne Twister algorithm (1997) was the standard PRNG for two decades, but modern browsers now use ChaCha20 or AES-CTR for their CSPRNGs.
Truly random number generation requires physical entropy sources — Intel CPUs use thermal noise from a resistor circuit via the RDRAND instruction.
