How it works

Random values come from window.crypto.getRandomValues(). Lists are shuffled with an unbiased Fisher–Yates process. For a wheel, the result is chosen before the animation; for weighted entries, each positive weight defines its share of the total probability.

Limits to understand

The included sets are not full language orthographies.
Case conversion follows browser Unicode rules.
Review accessibility before using single letters as the only cue.
