Aha. The menu in question is the Secondary Navigation, set to font weight 100, text transform uppercase, font size 13 px in the Customizer (typography section). I assumed those parameters would pass through to the footer bar with the menu content. (Not the color, of course, but the other settings.) Maybe assumptions should be the new paving material instead of intentions. 😉
Thanks for the assist, Tom! You folks redefine what “best” means when it comes to support.
