🔐 G100 Security Setup - Cloudflare Access

Zero-Trust Security für G100 MEGA ECOSYSTEM KONZEPT Phase

---

⚠️ WARUM SECURITY FIRST?

Das Problem

G100 ist ein KONZEPT in Early Stage:
├── Nicht production-ready
├── Enthält sensible Business-Logik
├── NDA-pflichtige Informationen
├── Team Collaboration nötig
└── Investor Präsentationen

❌ OHNE Security:
→ Jeder kann Docs lesen
→ API Endpoints öffentlich
→ Business-Logik sichtbar
→ NDA Verstöße möglich

Die Lösung: Cloudflare Access

✅ Zero-Trust Authentication
✅ Email-basierte One-Time PINs
✅ Keine Passwörter nötig
✅ 10-Minuten PIN Gültigkeit
✅ Whitelist für Email-Adressen
✅ Complete Audit Logs
✅ 50 Users kostenlos
✅ 5 Minuten Setup
