/* Kundenansicht neu: Wasser-Leiste (wasser-leiste.js). Pille aus Glas mit Wassertropfen, nach der Komponente „Nimbus UI · Liquid Navbar“
   (guglielmogiannattasio.it). Die Regeln der Pille sind die der Vorlage mit kn-wl-Namen; darunter der Einbau in die Hülle am Handy:
   Die Leiste ist keine weiße Zeile mehr, sondern eine schwebende Pille über dem Inhalt. Unterseiten (Etage 2) zeigen statt der Bereiche eine
   gläserne Pille mit „Zurück“ und Reitern; der aktive Reiter liegt in einem Tropfen wie der CSS-Tropfen der Pille. Lädt nach huelle.css. */
