UUID v7: Timestamp-ordered UUID (ms precision). Sortable by creation time, ideal for database primary keys.
ULID: 26-char Crockford base32 string. Lexicographically sortable, timestamp prefix, case-insensitive.
Nano ID: URL-safe compact ID with configurable length. 21 chars provides ~126 bits of entropy.
