Das ist der überarbeitete CSS-Code, bei dem alle Hintergründe auf **transparent** gesetzt und alle **Schatten** (`box-shadow`) entfernt wurden.

Ich habe die folgenden Klassen und Elemente angepasst:

  * **`body`**: Hintergrund entfernt.
  * **`.header`**: Hintergrund und Schatten entfernt.
  * **`.stream-title-section`**: Hintergrund und Schatten entfernt.
  * **`.stat-card`**: Hintergrund, Schatten und der Hover-Effekt-Schatten entfernt.
  * **`.now-playing`**: Hintergrund und Schatten entfernt.
  * **Media Queries**: Alle Ränder (`border`) wurden auf **transparent** gesetzt, falls sie zuvor eine Farbe der Seite verwendet haben (z.B. in `.grid-dj-profile`).
