+// Measure scroll position before and after Enter on a long thread.
+// The user's complaint: pressing Enter to submit makes the view "jump up".
+//
+// Steps:
+//   1. Scroll to the bottom of the thread
+//   2. Type a short message
+//   3. Record scroll position
+//   4. Hit Enter
+//   5. Record scroll position every 10ms for 1.5s after Enter
+//   6. Report deltas
+//
+// Usage:  node apps/desktop/scripts/measure-jump.mjs
