+"""Regression for issue #1982 — long model names are clipped with ellipsis in
+two surfaces (the model-picker dropdown items and the chat-header model
+indicator) with no tooltip, so the suffix/variant tag is undiscoverable.
+
+The fix adds a `title` (native hover tooltip) carrying the full name to both
+render sites in static/js/modelPicker.js. The module pulls in browser globals so
+it can't be imported under node; this guards the two title assignments at source.
