   Wie s2f-shell.css ein gekapseltes Modul: alles unter .s2f-page gescopt,
   damit es Bootstrap/style.css der noch nicht portierten Seiten nicht anfasst
   und umgekehrt nicht angefasst wird. Wird in partials/header.ejs global
   geladen — greift aber nur dort, wo ein .s2f-page-Wrapper existiert.

   Schriften kommen aus s2f-shell.css (@font-face), das auf denselben Seiten
   bereits geladen ist. Hier nur die Design-Tokens + Content-Stile.
