 * Seit Nachtrag 13 pflegt Marcel Referenzen als eigene Einträge im Portal (Titelbild, weitere
 * Bilder, beteiligte Marken). Solange dort nichts veröffentlicht ist, greift der Stand aus AP5:
 * die als „Realisiertes Projekt“ markierten Bilder aus den Markengalerien, über alle Marken
 * hinweg gesammelt. Visualisierungen und Entwürfe bleiben in beiden Fällen draußen.
