The period goes inside the quotation marks. That was my point.

That's stylistic more than grammatic. It is in fact logically incorrect
in this instance, where the quoted part is not itself a sentence; the
period is put (by some publishers) inside for looks primarily.

If you're discussing American English, you're incorrect. In England,
you're correct. But since the original poster and I are both posting
from the United States, that's the frame of reference I'm using. And
in the U.S., that's how it's done -- it isn't simply "for looks," as
you suggest.

Here's one of many references that concur:
