Hm, I did some further testing, and mixed things up I bit... to boggling results.
I left some of my font-family definitions in my main (linked) stylesheet, and transferred the others to my second (unlinked) stylesheet to use via the @import.
And in this case the KDP-generated e-book had all the font-family rules intact, even in the main CSS.
Could it be that, somehow, only a second dummy unlinked stylesheet has to exist in order for KDP to leave the main one alone? I'll do some more testing and report back...
