That worked, and just sent. When it wasn’t working, it was when I’d logged in to the WP FM Pro and submit through the Support interface, just fyi.
Note: Just for “fun,” I removed the custom html from the custom html field and put it in the append to template field, and the site properly stacked responsively. However, the call to the stylesheet and google font no longer worked, and the coded started about 200px from the top margin.
