-## Neue Features (Statistik Grafik Proxy)
-
-Dieses Release ergänzt eine serverseitige Proxy-Lösung für das interne Statistik-Portal, damit geschützte Diagramme sicher eingeblendet werden können, ohne Zugangsdaten im Browser zu speichern.
-
-- Was neu ist:
-  - Server-seitiger Proxy unter `/api/statistik/grafik` und Catch-all `/api/statistik/grafik/*`.
-  - Holt die Statistik-Seite mit Basic-Auth (serverseitig) und liefert sie an den Browser weiter.
-  - Schreibt die HTML-Antwort so um, dass relative Assets (CSS/JS/Images) über die Proxy-URL geladen werden (es wird ein `<base href="/api/statistik/grafik/">` eingefügt).
-  - Leitet auch AJAX-POSTs (z. B. `php/statistic.php`) weiter – Methoden und Bodies werden beibehalten.
-  - Entfernt framing-blockierende Header (z. B. `X-Frame-Options`, CSP-Meta-Tags) in der proxied HTML-Antwort.
-
-- Wichtige Environment-Variablen (nur serverseitig):
-  - `STATISTIK_GRAFIK_URL` — Basis-URL des internen Statistik-Portals (z. B. `https://sternwarte-welzheim.de/intern/statistik`).
-  - `STATISTIK_GRAFIK_USER` — Benutzername für Basic-Auth.
-  - `STATISTIK_GRAFIK_PASS` — Passwort für Basic-Auth.
-
-- UI-Änderung:
-  - Der `Grafik`-Button in der Statistik-Ansicht öffnet die Statistik jetzt in einem neuen Fenster (`window.open('/api/statistik/grafik', '_blank')`). Die vorherige iframe-Integration wurde entfernt, weil manche Browser (insbesondere Firefox und Safari) Probleme mit eingebetteten, geschützten Seiten machen.
-
-- Sicherheit & Hinweise:
-  - Setze die `STATISTIK_...` Variablen in deiner Server-Umgebung (Docker secrets oder im Host-Umfeld). Niemals Zugangsdaten ins Repository committen.
-  - Die Proxy-Route ist so konfiguriert, dass Assets und AJAX-Aufrufe über den gleichen Proxy laufen, damit die Seite vollständig funktioniert.
-
-Wenn du möchtest, pushe ich die Änderungen an `ANLEITUNG.md` in `origin/main` für dich.
-
-Optionales manuelles Deploy (falls Docker lokal verfügbar):
-
-```bash
-./deploy.sh 1.7.8
