Four flags run this page. Every module below is the same CTA block — what differs is which flag it listens to.

cta-visibility — a kill switch. Turn it off and this module is skipped entirely: no markup ships for it, nothing is hidden with CSS.

cta-regional-offer — regional content, served by audience rather than country. Four buckets, not two hundred and fifty. You are seeing the control.

cta-copy-test — the reassurance arm. A third of visitors see this one. Exposure is tracked in the browser, which is what lets a prerendered page host an experiment.

A proxy decides every flag, signs the answers into the URL, and serves the page built for that combination. There is a fifth module above this one — view the source and you will not find it.
