/* ══ Testimonial ════════════════════════════════════════════════════════════
   Reines Design-System: nicht das Bild bestimmt die Komposition, sondern ein
   Modul. Im Entwurf ist es 1/9 der Rahmenbreite, alle Ebenen liegen darauf.

     Ebene       Größe    Position (Modul)
     Portrait    2 × 2    0    / 0
     Zitatkarte  7 × 3    1,5  / 1,5   (grows with a long quote)
     Zitatmarke  1 × 1    8    / 1

   The card stays in the flow so a long quote makes the grid taller instead of
   running out of the card. Without a portrait (.no-portrait) the card starts
   in the left column and the attribution follows below it.
