/* The guides under /docs. Their look comes from the two logos they belong to: LunarSide's crescent moon and
   four-pointed star, violet on a night sky, and Luawe's, the same moon inside a dashed orbit. So the page is the
   night, the one bright colour is the moon's violet, lines that part things are dashed like the orbit, and a
   heading is marked with the star. Code is coloured as the game's own editor colours it. */
