/* =========================================
   Docked mode — clicking the avatar bubble moves .avatar-widget-panel out
   of the floating #avatarWidget and into #chatContainer (see the docking
   logic in index.html), filling the main chat area instead of staying a
   small bottom-right popup. .avatar-widget-panel.docked overrides the
   floating-panel rules above since the panel is no longer a descendant of
   .avatar-widget.open once it's moved.
