WordPress back-end developer — MemberPress paywall, SiteGround cache, structured data

Expert - Est. Budget: $2K Subscription articles are gated by MemberPress behind an intentional two-article meter. Two holes break it: SiteGround's full-page cache can serve a gated article in full to a visitor who arrives with no cookie, and the meter cookie is plain base64 and rewritable from the browser. The paywall is also not declared in structured data. Part A closes this. Part B installs four supplied page designs. Part B is installation, not design — markup, styles and copy are provided.
