   IHF DESIGN SYSTEM  ·  css/ihf-design.css
   ---------------------------------------------------------------------------
   The single source for the website's look.

   Everything visual is defined here once: the palette, the type scale, the
   spacing rhythm, and the components the pages are built from. Change a value
   at the top and it changes everywhere, because nothing below hard codes a
   colour or a size.

   Load order on every page:
       1. this file
       2. css/ihf-forms.css   (only on pages carrying a form)

   Nothing else is needed.
