Calculated screen coordinates from getBoundingClientRect() and dispatched mouse events via CDP Input.dispatchMouseEvent. Clicks never reached the deeply nested iframe (4+ frame layers). Tested 20 clicks on "Types of Teams" slide — stuck on same content every time. CDP mouse events don't reliably forward through nested cross-origin iframe boundaries.
