   Schimmel-Rechner (a_w-Wert / Temperaturfaktor f_Rsi)
   BGW-Fassung des EFD-Rechners (Seite 940, Stand 26.09.2026).
   Unterschiede zum Original: runde Formen und Feldoptik der BGW,
   Auswahl-Kästchen mit Abstand, BGW-Blau über --ef-gelb statt
   über die Akzentfarbe (die ist auf BGW blau), Überschriften ohne
   Großbuchstaben-Schreibmaschine.
