/* ============================================================================
   Snowdon, Inc. — rebuilt from the company's own archived site
   ----------------------------------------------------------------------------
   The 2011-2012 site survived in the Internet Archive, with its stylesheet, its
   logo and its photographs. The brand is therefore restored, not invented:

     navy   #002E66   headings, navigation, footer
     orange #DF8A1D   the rule under headings and the primary button
     blue   #5982B3   links and secondary accents
     pale   #B7CDEA   the light peak in the logo and panel rules
     type   Source Serif 4 for headings, Arial/Helvetica for text — the original
            used Arial throughout, with a serif wordmark

   The layout follows the original's shape: a white masthead with the mountain
   logo, a horizontal navigation line, a full-width hero, three therapeutic
   areas, the discovery platform, and a navy footer.
