   akonto · Grundlagen
   Design-Idee: das Kontoblatt. Blassgrünes Buchhaltungspapier,
   Haarlinien wie im Hauptbuch, Buchhalter-Rot als einziger Akzent,
   Ziffern immer tabellarisch ausgerichtet.

   Alle Schriften sind Systemschriften – es wird KEIN externer Dienst
   (z. B. Google Fonts) geladen. Das ist bewusst so: eingebundene
   Google-Fonts sind in Deutschland datenschutzrechtlich abgemahnt worden.
   Eigene Schrift gewünscht? Siehe docs/SCHRIFTEN.md
