/***
 * @module node-opcua-basic-types
 *
 * Cryptographically strong random bytes, from the one API that both runtimes agree on.
 *
 * This deliberately uses `globalThis.crypto.getRandomValues` rather than `node:crypto`:
 * node-opcua-basic-types sits at the bottom of the dependency graph and is pulled into
 * browser bundles, so it must not carry a Node built-in import that a bundler would have
 * to alias away, nor a dependency on a package whose browser entry drags in extra
 * modules. WebCrypto is a global in every browser and in Node.js since v18, so no
 * conditional export or `.browser` variant is needed here.
