/* The roadmap page (roadmap.html). Layers on the tokens in style.css, in the look of changelog.css: a panel head
   with the gold wash, then one vertical line of opaque cards on the plain ground. Phones get the line in the left
   gutter; from 900px it runs down the middle and the cards alternate sides (js/roadmap.js sets is-left / is-right on
   the VISIBLE cards, so a filtered view still alternates). Status is always words; a node's fill only echoes it. */
