Das `@app.get("/")` sagt **FastAPI**, dass die Funktion direkt darunter für die Bearbeitung von Anfragen zuständig ist, die an:

    Diese `@something`-Syntax wird in Python „Dekorator“ genannt.

In Python gibt es eine Möglichkeit, eine Instanz einer Klasse „aufrufbar“ („callable“) zu machen.

Nicht die Klasse selbst (die bereits aufrufbar ist), sondern eine Instanz dieser Klasse.

Dazu deklarieren wir eine Methode `__call__`:
