/* BoatLink demo UI — the boatlink.fi identity, worn by an application.
 *
 * One deliberate theme. The marketing site is night-watch dark with brass, and
 * an app that shares its name should feel like the same room - so every colour
 * is painted explicitly and there is no light variant to drift out of step.
 *
 * Type does the talking: Georgia for names and numerals (the same face as the
 * BL monogram), the system face for prose, and the platform mono for data,
 * because a bilge voltage is data and should look like it.
