 * pendulum, the tempo, three pills (time, clicks, sound) and, in the thumb's
 * reach at the bottom, Tap, Start and the mute. Everything else is in sheets
 * (app-shell.css, run by nav.js): time, clicks, sound, and Practice, which on
 * a wide screen is a drawer down the right. Light and dark come from theme.js;
 * every colour is drawn from the shell's tokens and --ab-accent.
