/* When chat is open, push the dashboard left by the chat panel's
   responsive width so content stays visible alongside the chat
   instead of hiding behind it. The padding-right values match the
   .chat-panel width breakpoints (defined further down) plus the
   default 32px gutter. Fullscreen chat suppresses the shift since
   the panel covers everything. Mobile (<768px) is also no-op since
   chat is a 100%-width takeover. We deliberately don't transition the
   padding — Chromium aborts the transition partway through when the
   chat panel's own transform animation runs simultaneously. The snap
   is barely perceptible alongside the panel's slide-in. */
