  style.css - the looks of the page. The colors, fonts and shapes follow the ones of gno.land so that the

  green of the Gno.land brand. It has a light and a dark version, chosen by the setting of your system.
  Nothing is loaded from other sites: if the fonts are not installed, the system fonts are used.
