Please explain this, as it is not something I've experienced in over 25
years of editing digital audio. There is no amplitude in the signal at
zero-crossing points, so how can it possibly result in a click?

Just because you're merging two clips at a zero crossing doesn't mean that
there isn't a difference in the DC levels of the two clips. It is the
difference in the DC levels of the two clips that causes the click, pop, or
thump.

If your editing software gently merges clips which is common, then it is
probably still creating some sort of thumping, but if the thumps are small
enough and at a low enough frequency, you don't hear them.
