/* The Atlas blog — on top of style.css (its tokens, fonts, header, buttons and footer).
   One idea carried through: the site's map. Each article's cover is a small map drawn from its address, the short
   version reads as stations along a line, and the chips wear the line colours — green for plain English, cyan for
   technical, pink for what's new. Dark only, like the rest of the site. */
