A play report about how the map looks arrives without the diagnostic that answers it, and the only way to ask for the line again is to wait for the player to play again. It cost a round trip on 2026-11-02, so the trace is unconditional now: one line per world-map selection change, with the frame the detail is drawn into added beside the detail frame's own rect, since a canvas zoom and an oversized tile change the picture the same way and only the two together say which one did it.
