// REST implementation of the repository seam: maps each semantic operation to the
// existing HTTP endpoint via `api/client`. This is the ONLY place that knows about
// URL paths, query strings, and multipart bodies. Behaviour here must stay a
// verbatim mirror of the calls the stores/views made before the seam existed — the
// web app is unchanged; the offline `local.ts` source (M10.5) is the alternative.
