/* ================================================================
   Gal Cohen — the project popup
   ================================================================

   Loaded by the site and by the project editor in wp-admin, so the popup an
   editor previews is the one a visitor gets rather than a second thing that
   looks similar. It carries its own copies of the four theme variables it
   uses: on the site they would be inherited from :root, and inside wp-admin
   there is no :root to inherit from — declaring them on .lightbox keeps them
   out of the admin's own styles.
