I recall reading somewhere that the KWZ-30 had a unique method of
handling AM signal fading. It wasn't synchronous detection but
something else. Does anyone remember what it was?

See page 13 here where it mentions the AM demodulator, that may be it:

That requires a lot of processing power. It would follow that
latency would be high. If you're using WWV as a time standard for
something requiring very high precision, it would require a
correction step.

Still, that's a pretty clever way of doing it.
