+/// The decision on a task of a comparison series: both chats side by side, read-only and without the names of the
+/// models, and the buttons of the vote.
+/// </summary>
+/// <remarks>
+/// The chats keep their places, the first chat on the left: the order in which the user met the models was drawn at
+/// random already, see ModelComparisonSeriesTask.FirstModelIsChatOne, and a vote names a chat, not a model. The chats
+/// stand side by side on wide windows and below each other on narrow ones, so that long answers stay readable, each
+/// with its button below it, as the answers in the mode Answer Variance, see ModelComparisonVoteColumns.
+/// </remarks>
