/* ==========================================================================
   mtsfj.github.io · the site's charter.
   The street at night, told the way the best product sites tell things: a deep
   ground, large soft light, a fine film grain, glass surfaces, big quiet type.
   The pixel font is the accent that ties every page to the street: titles,
   small labels, never running text.
   Every page links this file (after assets/fonts/fonts.css) and keeps in its own
   <style> only what is its own: the home's street, an article's widgets.
