Huh okay, moving to my other machine, the change to Noto Sans subtly
broke the homepage layout a bit, wrapping the form buttons to the next
line in the three module sections.
Here, I refactor to more modern grid/flexbox sensibilities. Btw, there
was a Flexbox thing that didn't work quite how I expected? I commented
on my confusion, but checked in Chrome and Firefox and it seems to work
in both, so, ok!
