 ### Changed
 
 - `Cuid`, `Cuid.generate`, `create_id`, and `cuid_wrapper` now enforce the CUID2 specification length bounds (`2..32`, i.e., `MIN_LENGTH`..`BIG_LENGTH`) and raise `ValueError` for length `1` and lengths `> 32` (previously a `FutureWarning` in 2.3.0 and `DeprecationWarning` in 2.0.3–2.2.1); the `cuid2` CLI likewise rejects lengths outside `2..32` with exit code 2.
