/* ==========================================================
   pieterwattel.nl - basic styling

   The page exists twice:
     .site-light  black text on white (the normal page)
     .site-dark   white text on black (a copy, laid on top)
   The slider (aside) reveals the dark copy by clipping it.
   To change colors, only edit --bg and --fg below.
