I have updated the brand.png logo to the 2020 version, and I have
made a small adjustment to the CSS to reflect its slightly larger
vertical height.
I also have made small tweaks to the system theme colors to use
the brand colors as recommended on page 5 of the logo usage
guidelines document avalible at
