// Arcadia storage configs API helpers.
//
// `GET /api/v1/storage_configs` and `POST /api/v1/storage_configs` are the
// only operations with full OpenAPI coverage today. Update/delete and the
// state-transition actions (activate, deactivate, mark-degraded,
// mark-maintenance, set-default, validate) are listed in the spec but their
// operations are still stubbed as `never`, so we hand-roll types and use the
// generic `arcadia.GET<T>` / `arcadia.POST<T>` / etc. — same pattern as
// `tenants.ts`. Switch to `arcadia.typed.*` when the spec gains coverage.
