// Author reads over REST — the twin of app/wix/blog/authors.ts. Same exports, same DTOs; the
// mappers come from authors-core (the SAME file the SDK transport uses, deployed flat next to this
// one). Both reads are non-fatal: authors are decoration on a card. Porting: keep the paths, keep
// the bodies, port the core once.
