// Author reads (Wix Members) — the only file that touches raw member entities on this transport.
// Goes over `wixFetch` (the SDK's own authenticated fetch, same identity as every module call)
// rather than the `@wix/members` module: the blog template does not depend on that package, and
// two small reads don't warrant it. The mappers live in ./authors-core (shared with the REST twin
// in templates/blog/rest/authors.ts). Both reads are non-fatal: authors are decoration.
