/* Kodza — Staggered Horizontal Menu
   A button that lets its links out one by one, the nearest first, and calls them back in
   reverse order when it closes; its label rolls from "Menu" to "Close". The links sit on the
   left of the button, or on its right with --right. Pure CSS motion, a few lines of JS.
   Everything is tuned with the --kz-stagger-* variables. */
