Description: The public-facing theme for the ENRFO platform. Built around the ENRFO palette — Deep Navy Blue, Power Blue, Electric Cyan, Deep Teal, Teal Green and Energy Green — and designed to hand members straight over to the ENRFO dashboard. Works on its own, and lights up extra sections when the ENRFO plugins are active.
