/**
 * radar.css — Radar Clock.
 *
 * Angle is time of day, radius is the child, and the sweep is the clock hand
 * pointing at now. Ported from frontend/lab/14-radar-clock.html.
 *
 * Everything is scoped under #screen-radar: the lab page owned the whole
 * document and set globals on html/body, which would have leaked across the
 * other nine screens.
