The next phrase combines text with a small rotating plus and the pointer. Agent cards then travel across a blue field.

      "handoff": "The 10.366667 s sample establishes the actual application sidebar after the second text hold. Subsequent samples show pointer movement and a highlighted Workspace agents row. The final 12.983333 s sample shows the builder; its interaction continues beyond the 13 s contract.",
