Implement cybernetwork background features: Add routes for serving cybernetwork CSS and JavaScript files, update base.html to include the new CSS and initialization script, and enhance style.css with smooth scrolling and background imports. This update improves the visual experience and functionality of the cybernetwork background in the application.

+# MindMapProjekt - Roadmap
+
+## Projektübersicht
+Das MindMapProjekt ist eine interaktive Plattform zum Visualisieren, Erforschen und Teilen von Wissen. Das Projekt wird umfassend überarbeitet, um ein modernes, benutzerfreundliches Design und erweiterte Funktionalitäten zu bieten.
+
+## Technischer Stack
+- **Backend**: Python/Flask
+- **Frontend**: 
+  - Tailwind CSS für moderne UI
+  - SVG-Bibliotheken für Visualisierungen (D3.js)

+Das Projekt enthält ein zentrales Verwaltungsskript `TOOLS.py`, das verschiedene Hilfsfunktionen bietet:
+
+#### Datenbankverwaltung
+- `python TOOLS.py db:fix` - Reparieren der Datenbankstruktur
+- `python TOOLS.py db:rebuild` - Datenbank neu aufbauen (löscht alle Daten!)
+- `python TOOLS.py db:test` - Datenbankverbindung und Modelle testen
+- `python TOOLS.py db:stats` - Datenbankstatistiken anzeigen
+
+#### Benutzerverwaltung
+- `python TOOLS.py user:list` - Alle Benutzer anzeigen
+- `python TOOLS.py user:create -u USERNAME -e EMAIL -p PASSWORD [-a]` - Neuen Benutzer erstellen
+- `python TOOLS.py user:admin` - Admin-Benutzer erstellen (admin/admin)
+- `python TOOLS.py user:reset-pw -u USERNAME -p NEWPASSWORD` - Benutzerpasswort zurücksetzen
+- `python TOOLS.py user:delete -u USERNAME` - Benutzer löschen
+
+#### Serververwaltung
+- `python TOOLS.py server:run [--host HOST] [--port PORT] [--no-debug]` - Entwicklungsserver starten
+

+# Anleitung: Animierter Netzwerk-Hintergrund
+
+Diese Anleitung erklärt, wie Sie ein Netzwerk-Bild als animierten Hintergrund für die gesamte Website einrichten können.
+
+## Option 1: Manuelle Installation
+
+1. Kopieren Sie das gewünschte Netzwerk-Bild (z.B. `d2efd014-1325-471f-b9a7-90d025eb81d6.png`) in die Datei `website/static/network-bg.jpg`.
+   
+   Sie können dafür das beiliegende Batch-Skript verwenden:
+   ```
+   copy-network-image.bat d2efd014-1325-471f-b9a7-90d025eb81d6.png
+   ```
+
+2. Starten Sie den Flask-Server mit dem folgenden Befehl:
+   ```
+   python start-flask-server.py
+   ```
+
+3. Öffnen Sie die Website unter http://127.0.0.1:5000/
+
+## Anpassung der Animation
+
+Sie können die Animation des Netzwerk-Hintergrunds anpassen, indem Sie die Datei `website/static/network-background.js` bearbeiten. Hier sind die wichtigsten Parameter:
+
+```javascript
+let animationSpeed = 0.0005; // Geschwindigkeit der Rotation
+let scaleSpeed = 0.0002;     // Geschwindigkeit der Skalierung
+let opacitySpeed = 0.0003;   // Geschwindigkeit der Transparenzänderung
+```
+
+## Animation der Mindmap-Verbindungen
+
+Die Verbindungen zwischen den Knoten in der Mindmap werden jetzt mit einer fließenden Animation dargestellt. Diese Animationen verbessern die Sichtbarkeit der Zusammenhänge und machen die Interaktion mit der Karte intuitiver.
+
+### Funktionen:
+
+1. **Animierte Linien**: Die Verbindungslinien zwischen den Knoten bewegen sich in einem fließenden Muster.
+2. **Hervorhebung bei Hover**: Beim Überfahren eines Knotens oder einer Verbindung mit der Maus werden diese hervorgehoben.
+3. **Kategorien-Beziehungen**: Die visuellen Verbindungen zwischen den Kategorien sind jetzt deutlicher erkennbar.
+
+## Position des Auswahlfelds
+
+Das Auswahlfeld auf der Karte wurde weiter nach links verschoben, sodass es vollständig sichtbar ist, wenn keine Auswahl getroffen wurde. Die Größe wurde ebenfalls angepasst, um die Lesbarkeit zu verbessern.
+
+## Wiederherstellung des ursprünglichen Hintergrunds (optional)
+
+Wenn Sie zum ursprünglichen Sternenhintergrund zurückkehren möchten, müssen Sie folgende Änderungen vornehmen:
+
+1. Bearbeiten Sie die Datei `website/templates/base.html` und ersetzen Sie:
+   ```html
+   <!-- Network Background Script -->
+   <script src="{{ url_for('static', filename='network-background.js') }}"></script>
+   ```
+   
+   mit:
+   ```html
+   <!-- Three.js für den Sternenhintergrund -->
+   <script src="{{ url_for('static', filename='three.min.js') }}"></script>
+   <script src="{{ url_for('static', filename='background.js') }}"></script>
+   ```
+
+2. Bearbeiten Sie die Datei `website/templates/mindmap.html` und entfernen Sie die Zeile:
+   ```html
+   <script src="{{ url_for('static', filename='network-animation.js') }}"></script>
+   ```
+
+3. Entfernen Sie den CSS-Code für `#mindmap-container::before` und die anderen netzwerkspezifischen Stile aus der Datei `website/templates/mindmap.html`.
+
+4. Starten Sie den Flask-Server neu, um die Änderungen zu übernehmen.
