/* AEVO Lernportal — "Prüfstempel" identity.
   A written exam is an official act: forms, paragraphs, a 70%-Bestehensgrenze,
   a stamp that says bestanden or nicht bestanden. The design leans into that
   register — paper, ink, a brass seal accent — instead of the generic
   Material/app-store look this screen used to clone. */
