...If Wikipedia is...a *starting* source from which you launch your digging, using its article citations to ferret out more details, then Wikipedia should be cited, whether you quote it or not.

Exactly. I don't think anything more than a statement that the Wikipedia article was consulted is necessary, if actual material from it is not used, but the viewing and reading of the Wikipedia article "to get ideas" or "identify sources" is precisely the issue. It is the "getting of ideas" without crediting the source of the ideas which is the issue.
