Pick the link for each Qualtrics page. Every condition uses two pages: the common part (same for everyone, trust set by the link) and one variant (from "View results" to the end).
Page 1 · Common: intro → tobacco & alcohol → “Answers saved”→Page 2 · Variant: View results → processing → report → thank you

How to use: “Copy iframe” copies the full Qualtrics embed code (same phone frame and mobile sizing as before) with the right link inside. Paste it into the question's HTML view.
Use the High trust common link (?trust=high) for the high-trust conditions (P2, P4, S2, S4) and the Low trust one for the others. Processing takes 30 s in every variant.
