Combining is specifically permitted. Paragraph 13 of AGPLv3 clearly states
(emphasis mine):

"Notwithstanding any other provision of this License, you have permission to
link **or combine** any covered work with a work licensed under version 3 of
the GNU General Public License into a single combined work, and to convey
the resulting work. The terms of this License will continue to apply to the
part which is the covered work, but the work with which it is combined will
remain governed by version 3 of the GNU General Public License."
