/* Jean de Dieu Ndayikeza: site styles (v2)

   Palette: ink, paper and red, plus a red-tinted "blush" for soft panels.
   Type: Bricolage Grotesque for headings, buttons and navigation;
         Newsreader for everything you read.
   Motif: the red sun. Hope rising. It appears once big (behind the hero photo)
          and then small: the logo dot, talk bullets, the route, the timeline. */
