 Die genaue Contao-, PHP- und Template-Version der öffentlichen Seite ist nicht verlässlich aus dem ausgelieferten HTML ableitbar. Das Setup bildet daher die wahrscheinlichste Komponentenfamilie nach; es ist kein Dump der Produktivinstallation. IONOS/Hosting, Matomo-Konfiguration, Inhalte, Templates und Erweiterungen müssen bei Bedarf separat ergänzt werden.
 
 Die Terminlogik liegt zunächst in `src/booking.ts`. Eine spätere Google-Calendar- oder Exchange-Anbindung sollte über eine Backend-API erfolgen, damit keine Secrets im Browser landen.

+## Versionierter Contao-Seitenzustand

+Die Contao-Seiten, Artikel und Layouts liegen in MariaDB und werden deshalb zusätzlich als bereinigter SQL-Seed versioniert. Details zu Export, Import und den bewusst ausgeschlossenen Daten stehen in [database/README.md](database/README.md).

+# Versionierter Contao-Seitenzustand
+
+`contao-baseline.sql` ist der versionierte Ausgangszustand für Theme, Layout, Seiten, Artikel, Inhaltselemente und später auch Formulare. Er ist für eine frische Contao-Datenbank bestimmt und enthält keine Benutzer, Passworthashes, Sitzungen, Logs, Cache-Daten oder Zugangsdaten.
+
+## Nach einer redaktionellen Änderung exportieren
+
+```powershell
+cd development-system
+.\scripts\Export-ContaoBaseline.ps1
+git diff -- database/contao-baseline.sql
+```
+
+Bei einer vorhandenen Datei fragt das Skript vor dem Überschreiben nach. Für einen bewusst nicht-interaktiven Export, z. B. in einer Automatisierung, `-Force` ergänzen. Den Diff vor dem Commit prüfen. Die Exportdatei enthält keine `tl_user`-Daten.
+
+## In eine frische Datenbank importieren
+
+Nach `contao-setup` und `contao:migrate`:
+
+```powershell
+cd development-system
+.\scripts\Import-ContaoBaseline.ps1
+docker compose exec app vendor/bin/contao-console contao:user:create --admin
+```
+
+Der Import bricht ab, wenn die versionierten Contao-Tabellen bereits Inhalte enthalten. Das verhindert ein versehentliches Überschreiben. Nur für ein bewusstes Zurücksetzen auf den Git-Stand ist Folgendes vorgesehen:
+
+```powershell
+.\scripts\Import-ContaoBaseline.ps1 -ReplaceExisting
+```
+
+`-ReplaceExisting` löscht ausschließlich Theme-, Layout-, Modul-, Seiten-, Artikel-, Inhaltselement- und Formulardaten. Benutzerkonten bleiben erhalten.
+
+## Medien
+
+Medien gehören als Dateien nach `development-system/files/` und werden in Git eingecheckt. Sobald Contao-Medien verwendet werden, muss der Seed zusätzlich die Metadaten aus `tl_files` enthalten. Das ist absichtlich noch nicht automatisiert, weil die aktuelle Datenbank nur Verweise auf nicht versionierte lokale Dateien enthält.
