/* Mobil: Fenster mit FESTER Höhe am unteren Bildschirmrand verankern.
   Eine definierte Höhe (statt height:auto) verhindert, dass das Fenster beim
   Absenden mitwächst – so bleiben Kopf oben und Eingabefeld unten immer sichtbar,
   und nur die Nachrichtenliste scrollt innen.
   Die Selektoren sprechen beide Positions-Varianten direkt an, damit sie
   die data-position-Regeln (right:0 / left:0) sicher überschreiben.
   dvh = tatsächlich sichtbarer Bereich auf Mobilgeräten (ohne Browserleisten). */
