/*
  /Company/ campaign layer (Binary Systems, Inc.)
  Loaded AFTER the five live stylesheets (bsimac, reset, text, 960, mobile).
  Type is the live site's: this file never sets font-family, font-size or
  font-weight, so body copy, headings and the menu keep the /css/text.css
  "Lucida Grande" stack and sizes (and the mobile.css phone sizes).
  The header and menu bar are untouched: every rule here is scoped to
  .co, .co-foot or .co-skip.
