+  <p>Goal: hover the trigger and wait until the <b>Confirm</b> button reveals (≥600ms dwell
+     with continuous <code>pointermove</code> activity inside the trigger), then click Confirm.
+     Instant hover-then-click without dwell, or hover with no intermediate pointermove,
+     looks robotic and fails.</p>
