/*
  Second Nature — stylesheet
  ---------------------------------------------------------------
  Rules I tried to keep:
   - one text column, notes live in the margin when there's room
   - rules (lines) instead of boxes, almost no shadows
   - one accent colour. it's red-brown. that's it.
   - if something needs a border-radius, it probably shouldn't exist
