/* lane.css — the two views.
 *
 * ONE STYLESHEET FOR BOTH, AND WHY
 * The advisor's phone and the porters' iPad show the same things — a request, a
 * person, how long something has been waiting — from opposite ends. If they had
 * separate stylesheets, "eleven minutes is orange" would eventually be true on
 * one screen and not the other, and the two people looking at them would be
 * having a disagreement the software caused. So the components are shared and
 * only the layout differs.
 *
 * THE SURFACE CLASS
 * `is-hand` and `is-desk` come from shared/device.js and mean "poked with a
 * finger" and "read with a mouse in reach". They are the only thing in here
 * that knows about hardware; everything else is composed from them.
