/* The Chain. ONE typeface, DejaVu Sans (the book interior's), in two weights.
 *
 * Three layers, like Rabbithole: a white page; a light grey panel (full width
 * on a phone, 1280px on a wide screen); and a navy oval that runs out past a
 * ring of dark chain. The ring's top five links are today's and fill in as
 * you play. Everything on a screen sits inside the ring: app.js sizes the
 * ring to the screen and shrinks the text block until its corners clear it. */
