The intended use of the CSSOM API is just to reflect the rule as it
was written in the stylesheet, and allow modification of it from

There are no "computed values" in at-rules like this - that's a
concept that only exists for property values.  Counter styles have an
*abstract* range, which is filled in by the 'range' descriptor and the
default behavior of the system.

In your example, asking for the 'range' descriptor would return "", as
it's not specified.
