Stands in for the real Wix site so the popup can be viewed locally. This block and the filler below are generated by build.sh and are not in 2-popup-custom-code.html. The popup appears after 15s or at 60% scroll depth, returns 20s after you dismiss it, and appears at most 2x per page view.
This block exists only so there is something to scroll through in preview. It has no bearing on the real site.
Keep scrolling to cross the 60% scroll-depth trigger threshold.
