Identifier of the Cuid2 library, the successor of cuid. It is a SHA-3 hash of a timestamp, a counter, a host fingerprint and random data, written in lowercase base36 after an initial random letter, so it reveals no creation time. The default length is 24 characters; applications can choose other lengths up to 32, which the regexp does not cover.
