/* PinRipple design system: the website, the app (with /app/app.css) and client reports (with /assets/report.css).
   One idea carries the look: a pin on a street map sending out ripples. Teal is the ripple (actions, links, gauges),
   orange is the pin ("you are here"), and the rank colours appear only where they mean a rank.
   Light is the default look; the moon/sun button switches to dark (data-theme on <html>, saved on that device by theme.js). */
