Generates random tokens, UUIDs, and secrets using the browser's built-in cryptographic PRNG, not Math.random().
Tokens and UUIDs are generated using cryptographically secure PRNGs via window.crypto, not Math.random(), which is not cryptographically safe.
Decoded locally in your browser. The token never leaves your device.
Generated client-side using crypto.getRandomValues, no server calls.
