Namespace providing type guards and runtime-checked casts for the branded
length-constrained string types (MinLengthString, MaxLengthString,
BoundedLengthString, FixedLengthString).
Lengths are measured in UTF-16 code units (the same unit as
String.prototype.length), so characters outside the Basic Multilingual
Plane (e.g. emoji) count as 2.
