split-box-sz-string

A class string passed to splitBoxSz, which takes sz objects.

• It is thrown as an error whose code is this id, by a development build; a production build does not throw it.

Message

A name in angle brackets is a value the message fills in.

[csszyx] split-box-sz-string: `splitBoxSz` partitions sz objects, not class strings, so it cannot split `<value>`.
  help: use `splitBox()` for a class string.
  note: a production build drops the string instead of throwing.
