 * a new Guid, made of 16 bytes drawn from the platform CSPRNG
 * (`crypto.getRandomValues`, under Node.js as well as in the browser).
 *
 * The 128 bits are fully random: no RFC 4122 version or variant bits are carved out,
 * so a Guid produced here is unpredictable to the full width of its value. It is
 * therefore safe to use where the identifier must not be guessable — a SessionId, or
 * the requestId of OPC 10000-12 §7.9.5 FinishRequest.
 *
 * Note that the other `random*` helpers of this module (randomByteString, randomString,
 * randomUInt32, ...) are fuzzing helpers built on Math.random and carry no such
 * guarantee — see {@link getRandomInt}.
