   PEARL SKIN — Auftragsrausch Landing v5
   Poliertes Perlmutt-Metall statt stumpfem Grau: helle,
   glänzende Premium-Oberflächen (polished pearl metal, soft
   liquid chrome, frosted glass), feine Lichtkanten oben links,
   dunklere Kanten unten rechts, dezenter irisierender Schimmer
   und leuchtende Blau/Türkis-Signale.
   Letztes Basis-Stylesheet -> Overrides gewinnen. KEINE Token-
