/* ==========================================================================
   Flambeau deck styles. Every deck links this file and /deck/deck.js.
   Every slide is a fixed 1600x900 canvas that deck.js scales to fit the
   window, like a slide in Keynote: layouts never reflow and never scroll.
   The aurora background fills the whole window around the canvas.
   Inside a slide, size things in rem (1rem = 24px of the 1600px canvas) or
   in cqw/cqh (percent of the canvas); never in vw/vh.
