   Type      : Instrument Serif (display) + Archivo (text)
   Radius    : three decisive values only — 0, pill, petal.
               The petal comes from the peony mark: one pair of
               corners fully swollen, the other pair cut square.
               No 8px mush anywhere.
   Colour    : warm paper, ink, one carmine drawn from the flower.
