/* ══════════════════════════════════════════════════════════════════════════
   ambient-fergi-rail.css — the Ambient Fergi rail, in every non-Fergi room.

   Train: porting-perimeter-souls S8. Component: app/js/features/ambient-fergi-rail.js

   THE RAIL IS WORKSPACE, NOT CHASSIS. It is the first row of the room's own
   working panel, not part of the sculpted perimeter — so nothing in this file
   touches `.ffvc-*`, `.ffrw-header`, a keep-out, or any measured geometry. The
   ten ported rooms' capture gates and derived keep-outs are untouched by
   construction; this session wrote no theme and no chassis rule.

   IT ALSO DOES NOT COMPETE WITH THE ROOM. One line of controls, one line of
   answer, the room's own colours, and no border that reads as a second window
   inside the window. A rail that announced itself would be exactly the
   "decorative label competing with the artwork" the fleet's law refuses.

   Fergi saying it could not think. A SECOND line under the answer, deliberately
   quieter than the answer it qualifies: the member still got a real filtered
   list, and this explains why it is a plain one — it does not take the result
   away. Warning-amber would over-read it (a literal fallback is a bad answer,
   not a failure) so it stays in the secondary text colour, set apart by the
