/* ============================================================================
   Client chat — Pages/Chat.razor and Pages/Admin/ClientChatRooms.razor.

   Rooms · conversation · people/thread, as three cards side by side on a desktop,
   the side panel as a drawer on a tablet, and one column at a time on a phone (the
   list, or the room with a back button). Every colour is a token, so both themes
   come for free.

   The page fills the canvas exactly and the message list scrolls inside it, the
   way a chat app behaves — the page itself never scrolls, so the composer is
   always under the thumb.
