/* Many Happy Orbits: the planet-age calculator.
   Layout: one column of reading width; the calculator opens wide, with the orbit rings
   beside their numbers (stacked on phones). The rings are the one loud thing; everything else is quiet.
   Dark-first: a night ground lit by the Sun's gold, each world in its own colour. */
