/* --- 3D-Buch-Effekt (wiederverwendbar) -------------------------------
   Macht ein Cover wie ein echtes Buch (Seitenschnitt rechts + Schatten).
   Verwendung: auf einen Wrapper legen, der GENAU EIN <img> enthält:

     <div class="book3d"><img src="cover.png" alt="..."></div>

   Hinweise:
   - Der Wrapper braucht Platz nach rechts/unten (KEIN overflow:hidden),
     da der Seitenschnitt rechts heraussteht.
   - Für die kleinen Slider-/Grid-Karten (mit overflow + Hover-Zoom) ist der
     Effekt NICHT gedacht – dort bleiben die Cover flach.
   - Stärke/Optik zentral hier anpassbar (Dicke, Versatz, Neigung, Papierfarbe).
