Merge branch 'reduce-font-size' into 'master'

Reduce base font sizes across app by 1px

Looking at other websites that use system fonts, the default seems to be `14px`. We currently use `15px` which feels a little too big at the moment (in my opinion). This is just an idea so feel free to close it @awhildy 😄
