/* THE MARS CHART'S LOOK (05-13 AT-09), shared by the home page and the Mars Atlas page.
   Step 1. The sheet: the printed map, its two plates (ancient sea and dry), and the drawing on top.
   Step 2. Motion: the shore inking itself in, the sea draining (a canvas laid over the sheets), routes drawing out, ships
           hopping along them, the first ship coming down, pins dropping with a ripple, the city's glow, and a slow beat
           round the visitor's home. Less motion: none of it.
   Step 3. The time ribbon: a line with one stop per era, a fill that follows time, and a play button.
   Step 4. The place card that opens beside a tapped place, printed like the map. The night shade, the Sun mark and the
           settlements' lights (Step 1) are drawn live by chart.js.
   Step 6. The living atlas (05-13 AT-24, AT-25): the corner with its Live badge, Spin a day and the lens button; the
           Sun's chevrons, frost crystals, storm haze, gliding moons and Phobos's shadow; inked routes and wax seals;
           the impact replays; and the brass lens.
   Colours come from 05-13's numbers.chart, set on the chart as --wc-ink and --wc-paper. */
