/* ============================================================
   Design 3.0 — „Neues Design" (Einstellungen → Allgemein → Darstellung).
   Schicht ÜBER modern.css: nur unter html.d3 (die Klasse setzt index.html
   früh, zusammen mit .modern). Ohne die Klasse greift KEINE Regel → exakt
   Design 2.0.

   Leitbild: ruhig, klar, hochwertig. Eine Schrift auf allen Geräten (Inter,
   lokal mitgeliefert, lädt nur hier), neutrale Graphit-Töne statt Blaustich,
   feinere Linien, Abschnittsköpfe in normaler Schreibweise statt
   GROSSBUCHSTABEN, einheitliche Höhen (Knopf/Feld 34 px, Handy 40 px),
   Symbole auf Kacheln, weichere Schatten nur auf schwebenden Flächen.

   Performance-Regeln wie modern.css (gemessen 11.10.): KEIN backdrop-filter,
   KEINE filter, KEIN ::selection, KEIN :has(), KEINE Dauer-Animationen,
   KEINE Schatten auf Baum-/Listenzeilen, Transitions nur auf Hover.
