   DIRECTION A3 — OWL NAVY & CRITERION GOLD
   Every colour below is sampled from the Operant Learner logo
   (images/operant-learner-logo.svg): navy rgb(0,56,118) = #003876,
   blue rgb(14,72,143) = #0E488F, gold rgb(219,141,3) = #DB8D03,
   pale blue rgb(140,167,208) = #8CA7D0, cream rgb(239,200,132) = #EFC884.
   They are the same values the portal already uses (css/styles.css
   --primary-color / --primary-light / --secondary-color / --secondary-light).
   Shared by / (landing.html) and /ceu (ceu.html).
