/* FIB Stil A "Behörden-Hightech": gemeinsame Basis für die öffentlichen Seiten (Startseite, Zwischenseiten, Rechtliches).
   Richtung A, gewählt von Leon am 26.10.2026. Grundlage sind die Blau-Silber-Werte der Tokens (static/fib-tokens.css, Variante D).
   Nur lokale Schriften (static/fib-fonts.css) und eigene Grafiken, keine externen Ressourcen (CSP 'self').
   Animiert werden nur transform und opacity; prefers-reduced-motion schaltet alles ab (Ende der Datei). */
