/* DEMO C2 · Vòng thẻ quanh Trái Đất — loaded after journey.css on /ve-pow/demo-c2/ only.
   Boarding = the Earth in the middle, a thin dashed orbit and ten cards on it. The card in front is big, flat and easy to read; its neighbours are smaller; the far ones are a number and a label.
   Phones and tablets: the Earth on top with a tilted orbit and ten dots, one large card under it in a swipe-snap row. (Dark only, not themed: the test walkers skip /ve-pow/.)
   The cabin is pinned to the viewport, so the numbers JS puts in --c2-* (centre of the Earth, its radius, the ellipse of the orbit) are viewport pixels. */
