   Eigenständiges Stylesheet für die Nicht-Deck-Seiten der Presentation-
   Site (Gallery-Startseite, Login). Übernimmt das Designsystem des
   reveal.js-Themes ("Designsystem Frank Nägler", Variante 1a): Papier und
   Tinte, Petrol als Akzent, Archivo/Instrument Sans, flach, keine Schatten
   und keine Verläufe — für einen konsistenten Auftritt.
