   flow.css — stacked scrolling layout for smaller screens
   Phones, tablets, foldables and any window below 1280×720.
   The same scenes as the canvas layout, stacked as one page.

   THE BREAKPOINT LIVES HERE AND ONLY HERE. The media query
   sets --layout: flow, which js/canvas.js reads. Change the
   numbers below and both CSS and JS follow.

   Everything in this file is inside the media query, so the
   desktop canvas layout is untouched.
