Silent 39-second demo. Claude Code is asked to check Product Hunt notifications in a signed-in Firefox. The agent opens the notifications page, takes an accessibility snapshot (each element gets a stable ref), opens the launch thread, reads it, and answers that nothing needs a reply. Every frame is a screenshot the extension took of the page it was driving.
