give ARIA banner role to header
replace hardcoded source image with text
some basic flex stuff
everybody needs some class(es)
20px isn't that bad of a type size at all
playing around with background images for the banner image
Eventual goal is to have the small screen view be a faded version of the site's colour palette, selected from colours in my headshot. The headshot will appear at wider screen sizes, as the banner becomes a sidebar.
