   To retheme the entire site, change the values below.

   Sampled from the FCSI logo gradient (#0082b8 -> #c8e6f1).
   The action blue is one shade darker than the logo blue on
   purpose: white text on #0082b8 measures 4.3:1 and fails
   WCAG AA, while #0075a8 gives 5.1:1 and passes. The logo
   artwork itself is untouched.
