Smaller font
This shrinks the main font sizes in a simple way.
First, the few main font-size elements are changed to "1em".
Second, the rem-base
variable is set to be 16 (as in 16px), which causes much of the site to scale smaller.
This MR does not attempt to remove the use of rem units throughout; it is designed to be quick and easy shrinkage of the fonts. More refactoring can come in later MRs.
