Yes, I know that, but it doesn't tell me which faces are used for which
purposes within gnus, nor anywhere else.

Yes, these are the ones that I've been focusing on. However, there are
something like 16 of them, and it's a matter of trial and error for me
to determine which are used for which purpose under gnus.

Aha! That's it! It tells me that one of the faces I'm interested in is
called `gnus-group-mail-3-empty-face'. It would have taken me around 6
or 7 more trial-and-error attempts before I got to this one.

How can I know when `*-mail-1-*', `*-mail-2-*', or `*-mail-3-*' are used
for any given header? Do I have to determine this by reading the gnus
source code, or is it documented somewhere else?

But from now on, I'll use `C-u C-x ='.

Thanks!
