9Constraints specify what values are allowed.
10To CUE they are just values like anything else,
11but conceptually they can be explained as something in between types and
12concrete values.

14But constraints can also reduce boilerplate.
15If a constraint defines a concrete value, there is no need
16to specify it in values to which this constraint applies.
