/* Hero-Überschrift bewusst auf max. 36px begrenzt (nicht 4rem/4.5rem).
   Bis zum libs.js-Rollout (05.08.2026) lud die Seite ungewollt die Framework-Regel
   `body h1 { clamp(2rem, 4vw, 36px) }` aus libs.css mit; deren höhere Spezifität
   (0-0-2) überschrieb die frühere DRK-Regel und ergab faktisch diese 36px.
   Andreas hat den kleineren Wert im Screenshot-Vergleich als den besseren bestätigt
   ("die 36px vorher sind besser"). Seit libs.css weg ist, steht der Wert hier fest
   im eigenen Stylesheet — NICHT zurück auf 4rem/4.5rem "korrigieren". */
