/* =========================================================================
   Outreach Trust-Landingpage - Basis-Stylesheet (v4, "richtige Website"-Look
   mit mehr Farbe/Leben in den Content-Sektionen statt Weiß/Grau-Monotonie)
   Eigenständige Optik: nicht Leads-Pirates-Branding, nicht 1:1 Kunden-Branding.
   Struktur angelehnt an eine klassische B2B-Landingpage (Header/Nav, Hero,
   Ergebnisse, Zielgruppen, Ausgangslage, Kontaktperson, Ablauf, CTA, Footer).
   Farben werden zur Laufzeit teilweise aus assets/config.js gesetzt (main.js).
