+## 5.75.1
+**`(fix):`** Fix `fern docs theme upload` failing with a 422 "Content has not been uploaded" error
+when binding theme assets. The content-existence check now uses the org-scoped registry
+content path so uploaded content is stored under the same org as the subsequent file bind.
+
+
+**`(fix):`** Fix `fern docs theme upload` always targeting the production registry regardless of the
+CLI build environment. It now falls back to `DEFAULT_FDR_ORIGIN` (the origin configured for
+the CLI build, e.g. dev) like other CLI services, so a dev-CLI login token is no longer sent
+to the production registry (which returned 403 "Failed to resolve organizations").
