/**
 * WorkspaceDeck — die Workbench: Vollbild-Panels + Taskleisten-Dock unten.
 *
 * Statt einer Zoom-Landkarte: jedes Panel ist bildschirmfuellend und Handy-
 * optimiert, das Dock wechselt per Daumen-Tap sofort. Alle Panels sind IMMER
 * gemountet (nur das aktive ist via display sichtbar) → kein Remount, Chat
 * behaelt RVS/Audio/Queue, WebViews behalten ihren Zustand.
 *
 * Bei offener Tastatur blendet das Dock aus (mehr Platz zum Tippen).
