// Current-member read (Wix Members) over the SDK — the only file that touches raw member entities
// on this transport. The DTO mapper lives in ./members-core (shared with the REST twin in
// templates/members/rest/members.ts); this file is the transport only. Identity vs. profile are
// different layers: "is this caller logged in?" needs no app install, but getCurrentMember returns
// profile DATA only once the Wix Members Area app is installed (the seed installs it). Copy as-is;
// extend by adding functions, not by editing these.

 * The current member, or null for an anonymous visitor — and null for a LOGGED-IN member

 * Never throws: anonymous is a normal state for the client-side custom-login gate.
 * The SDK export is getCurrentMember — the REST name "Get My Member" does not exist on
 * the module; getMyMember(...) throws `is not a function`, and only once a real member
 * loads the page.
