/* ── investition.css — „Einstieg & Investition" (Variante C, NEU) ─────────────
   Schließt die im Briefing geforderte Führung durch „Angebot, Preise, Prozesse"
   (UX-Finding 3). Zwei klar getrennte Ebenen: (1) der produktisierte Einstieg
   (AI Visibility Audit) + Gesprächs-Alternative, (2) die Investitionsrahmen der
   laufenden Zusammenarbeit als Orientierung — keine SaaS-Pakete.
