    How it works

    • Randomness comes from crypto.getRandomValues() with rejection sampling, so every character is uniformly distributed — no modulo bias.
    • At least one character from each selected set is guaranteed, then the result is shuffled.
    • Strength is estimated as length × log₂(pool size). Aim for 80+ bits for important accounts.
