aiBuildStructureFromSourceLandingPage
Landing-page twin of aiBuildStructureFromSource: reconstruct the V46 landing page layout from a source (pasted HTML or a URL) through the SAME generic DomStructureBuilder + source-grounded refiner, create it via the SAME CreateLandingPage path (draft revision, server-stamped schema version), and return the created landing page. Same alpha gating, kill switch, and per-user hourly rate limit as the email flow.
