/* =====================================================================
   SNU faculty websites
   Loaded after the main stylesheets on /faculties/<slug>/ pages only.
   Keeps the main site's components and typography; adds the faculty palette,
   header and the blocks carried over from the faculty layout.

   Palette: blue #3A88E9, navy #0F2C59, gold #E5A93B. White text on #3A88E9
   is below WCAG AA (3.5:1), so buttons and text links use the darker blue
   #2972CF / #1F5DAB and the navigation bar uses navy.
