/*
  Skritt - designsystem
  Identitet: fiberselskapets eget produkt er lys-signaler i glassfiber;
  konkurransen handler om kroppens egen puls av skritt. Signaturelementet
  er "pulslinjen" - en tynn, reisende lysbølge (samme visuelle idé som et
  optisk signal) som ligger under store talltavler og fungerer som appens
  gjenkjennelige strek. Alt annet holdes rolig og disiplinert rundt den.
