/* ============================================================
   BUREAU OF LOST TIMELINES — DIVISION ROOMS (rooms.html)
   Version: 2.0 (Dossier system)

   A room is a wire, not a record sheet, so it is the one surface in the
   Bureau that reads as two columns: the lines you belong to on the left,
   the traffic on the selected line on the right. Everything else about it
   is still Bureau paper — ink panel, hairline rules, a coloured rail down
   the left of a row.

   Colours keep their Bureau meanings: purple (the posting token) is a thing
   you belong to, phosphor is the machine confirming itself — a line you sent,
   a count of new traffic — amber is a section that is still open, and the
   deep red of a seal is only ever used on a closed room.
