/* ==========================================================================
   Footnotes
   Styles the markup Ghost's Markdown card produces from [^1] syntax
   (markdown-it-footnote): sup.footnote-ref, hr.footnotes-sep,
   section.footnotes > ol.footnotes-list > li.footnote-item, a.footnote-backref.
   Loaded directly from default.hbs, outside the Gulp build.
   Selectors are written at ol.footnotes-list / li.footnote-item specificity
   so they win over the older footnote rules in Ghost's Code Injection.
