/* InomERP Chat — Whiteboard
   =========================================================================
   Layout and tokens follow the approved prototype: a light workspace, not the
   dark call overlay the earlier build used.

       header
       ├── left 205px   pages + tools
       ├── center       toolbar 52px + board area
       └── right 315px  participants
       bottom 112px     call controls

   Everything is scoped under .icbw so it cannot leak into the chat portal,
   which shares the page.
