   1) .bb-ghost + .bb-ghost-word — atmosphärische Riesen-Hintergrund-Typografie
      als Brücke zwischen Sektionen (unten am Übergang natürlich beschnitten).
   2) .bb-dark-band — ruhige, studio-dunkle Premium-Fläche (Petrol-kompatibel).
   Anwendung: <div class="bb-ghost" aria-hidden="true"><p class="bb-ghost-word">WORT</p></div>
   direkt VOR einer Sektion platzieren; für den Hell→Dunkel-Übergang die
   Folge-Sektion als .bb-dark-band ausführen. */
