Title:        Site styles — slate grey, teal and amber, set large for easy reading
Description:  Built for older eyes: an 18px base, generous line height, strong contrast, links that
              are always underlined in body text, and buttons and form controls big enough to hit
              first time. Class names keep the bi- prefix of the fleet skeleton; gs- is this site's.
