   Ponderosa Trail Systems — shared design system

   Lettering: Archivo (display, variable width) for headlines,
              Figtree for text, Caveat Brush for the signature only.
   Shape:     "leaf" corners (one large and one small radius on
              opposite corners, taken from the logo's diamond),
              pill-shaped buttons and chips, and angular ridge-line
              edges between sections instead of hard horizontal rules.
