/* Argos — styles.
   Same family as the Rooted and Girl-Gorithms sites: a coloured rule over a white
   masthead, the device's standard font, square buttons, ruled cards with a
   coloured top edge, corner-bracket frames and a deep footer. The colours come
   from the Argos logo: teal and black on white. Pages put content on the left and
   small boxes in a sidebar on the right. */
