+# Frontend Erklärung (für Einsteiger)
+
+Dieses Dokument erklärt die Logik und Struktur des Frontends. Es basiert auf **Next.js** (einem React Framework) und **TypeScript**.
+
+## 1. Grundkonzept: Komponenten
+Die gesamte Anwendung besteht aus kleinen, wiederverwendbaren Bausteinen, sogenannten **Komponenten**.
+Stell dir das wie Lego vor: Ein "Knopf" ist ein Stein, ein "Formular" ist eine kleine Platte aus Steinen, und die "Seite" ist das fertige Haus.
+
+**Warum?**
+-   Übersichtlichkeit: Man muss nicht 1000 Zeilen Code auf einmal verstehen, sondern nur kleine Teile.
+-   Wiederverwendbarkeit: Ein Knopf wird einmal programmiert und überall benutzt.
+
+## 2. Der Startpunkt: `layout.tsx` und `page.tsx`
+
+### `app/layout.tsx` (Der Rahmen)
+Dies ist die "Hülle" um jede Seite.
+-   Hier wird HTML, Body und CSS geladen.
+-   **Wichtig:** Hier sitzt der `NextAuthSessionProvider`. Das ist wie ein unsichtbarer "Rucksack", der die Login-Informationen (Session) trägt und sie überall in der App verfügbar macht.
+
+### `app/page.tsx` (Der Inhalt)
+Dies ist die Startseite. Sie entscheidet, was angezeigt wird:
+1.  **Nicht eingeloggt?** -> Zeige den Login-Screen (`AuthScreen`).
+2.  **Eingeloggt als Lehrer?** -> Zeige das Lehrer-Dashboard.
+3.  **Eingeloggt als Raumbetreuer?** -> Zeige das Betreuer-Dashboard.
+
+**Warum?**
+So haben wir eine einzige URL (Startseite), die sich aber intelligent an den Nutzer anpasst ("Conditional Rendering").
+
+## 3. Das Gehirn der App: `lib/auth-context.tsx`
+
+Hier liegt die wichtigste Logik. Wir nutzen einen **React Context**.
+Normalerweise müsstest du Daten (z.B. "Wer ist eingeloggt?") von oben nach unten durch alle Komponenten durchreichen ("Prop Drilling"). Das ist mühsam.
+Der Context ist wie ein **globaler Speicher**, auf den jede Komponente direkt zugreifen kann.
+
+**Was passiert hier?**
+-   **Zustand (State)**: Hier merken wir uns:
+    -   `user`: Wer ist gerade da?
+    -   `tickets`: Liste aller Tickets.
+    -   `rooms`: Liste aller Räume.
+-   **Aktionen**: Hier liegen die Funktionen wie `login()`, `createTicket()`, `updateTicketStatus()`.
+    -   Diese Funktionen sprechen mit dem Backend (dem Server) über `fetch`.
+
+**Beispiel:**
+Wenn du auf "Ticket erstellen" klickst, ruft die Komponente `createTicket()` im Context auf. Der Context sendet die Daten an den Server und lädt danach die Ticketliste neu (`fetchTickets`). Alle Komponenten, die die Ticketliste anzeigen, aktualisieren sich dann automatisch.
+
+## 4. Die Verbindung zum Backend: Authentifizierung
+
+Wir nutzen **NextAuth.js**.
+-   **Frontend**: Wenn du dich einloggst, schicken wir Benutzername/Passwort an NextAuth.
+-   **Backend (Java)**: Unser Backend prüft die Daten und gibt einen "Token" (Ausweis) zurück.
+-   **Session**: NextAuth speichert diesen "Ausweis" sicher. Bei jeder Anfrage an den Server (z.B. "Lade Tickets") zeigen wir diesen Ausweis vor (`Authorization` Header).
+
+## 5. Warum TypeScript?
+
+TypeScript ist JavaScript mit "Typen".
+Statt einfach eine Variable `data` zu haben (wo alles drin sein könnte: Text, Zahl, oder nichts), definieren wir genau:
+`interface Ticket { id: number; title: string; status: 'OPEN' | 'CLOSED'; }`
+
+**Warum?**
+-   **Fehlerschutz**: Wenn du versuchst, einem Ticket einen Namen statt einer ID zu geben, unterstreicht TypeScript das rot – *bevor* du das Programm überhaupt startest.
+-   **Autovervollständigung**: Der Code-Editor weiß genau, welche Eigenschaften ein Ticket hat und schlägt sie dir vor. Das macht das Programmieren viel schneller und sicherer.
+
+## Zusammenfassung
+1.  Der Nutzer öffnet die Seite (`page.tsx`).
+2.  Der `AuthContext` prüft: "Kenne ich dich?".
+3.  Nein? -> Login Formular.
+4.  Ja? -> Dashboard anzeigen.
+5.  Das Dashboard holt sich Daten (Tickets) aus dem `AuthContext`.
+6.  Der `AuthContext` hat die Daten vorher vom Server geladen.
