   Eine Schriftart für alles: Manrope, optimiert auf Performance
   - 3 Gewichte als Dateien (400, 700, 800) – statt 5 (500 und 600 weggelassen)
   - Body-Text = 400, kräftigere Akzente = 700, Display/Headlines = 800
   - Jede Datei enthält latin + latin-ext kombiniert (vom GWFH so geliefert)
   - Format: WOFF2 only (von allen modernen Browsern unterstützt)
   - font-display: swap = Text sofort lesbar (FOUT statt FOIT)
   - DSGVO: keine Anfrage an Google-CDNs
