/*
  SEAN PLETZ | PORTFOLIO PROTOTYPE
  ---------------------------------------------------------------
  Quick changes:
  1. Colors and spacing live in :root immediately below.
  2. Cover movement is controlled in ../js/main.js under PROJECT FLIGHT.
  3. Disable Play by adding `hidden` to its nav item and section in index.html.
  4. Red .todo text on case studies marks content Sean should replace.
