/*
  Style sheet for the Starred Inkwell website

  This file defines the visual presentation for all pages in the site.  It
  includes a small CSS reset, a set of variables for colour and spacing,
  responsive navigation styles, section layouts, cards and forms.  The
  design takes cues from modern digital agencies while maintaining a
  distinct identity rooted in literature and nature.  Media queries at the
  bottom of the file adjust the layout on tablets and phones.
