  /* Antworten zweispaltig statt als lange Liste.

     ROOT CAUSE des horizontalen Overflows bei 390 px (§15): Grid-Items haben
     implizit min-width:auto und können deshalb NICHT unter ihre
     Min-Content-Breite schrumpfen. Ein langes Antwortlabel erzwang 190 px; die
     beiden 1fr-Spalten ergaben zusammen 356 px in einem 296 px breiten
     Hinweisfeld. Der Überlauf schob die gesamte Seite auf 403 px. Unterhalb von
     380 px griff die einspaltige Regel, weshalb 375/360/320 unauffällig blieben
     und ausgerechnet 390 px betroffen war.

     Behoben an der Ursache: minmax(0, 1fr) hebt die Mindestbreite auf, und
     overflow-wrap erlaubt dem langen Wort einen Umbruch statt eines erzwungenen
     Mindestmaßes. Kein Abschneiden, kein overflow:hidden. */
