/* ============================================
   AIR2O — Main Stylesheet
   ============================================

   HOW TO EDIT:

   COLORS — Change the variables below in :root to
   update colors globally across the entire site.

   FONTS — Change --font to swap the typeface.
   When you license Maison Neue, replace the
   Google Fonts link in index.html and update
   --font to: 'Maison Neue', sans-serif

   SPACING — Section padding is controlled by
   .section { padding: 140px 0; }

   LAYOUT — Max content width is set in .container
