+/// Claude, all of it: the 3.x models, the 4.x models, and the 5 line.
+/// </summary>
+/// <remarks>
+/// One family, because every Claude is the same shape and always has been -- text and images in,
+/// text out, tool calling, one API. What each generation adds to that is a single sentence about
+/// thinking, and the rules below are almost nothing but those sentences.
+///
+/// The first rule is the family's own fallback, and it is a statement rather than an accident: a
+/// Claude nobody has written a rule for yet is still a Claude, and every one of them so far reads
+/// images and calls tools. It answers for whole name parts, so every rule bound to the start of a
+/// name beats it, whatever their lengths -- which is what lets it sit first and mean "unless".
