+## Git-source WebUI package
+
+The repository root exposes `@govoplan/workflow-webui` for Git-tagged release
+dependencies. It mirrors the owning `webui/package.json` version, public
+TypeScript/CSS exports and peer requirements, with entry paths under
+`webui/src`. Consumers provide the shared Core/React peers; the facade runs no
+development or install scripts. The source archive contains `webui/src`, this
+README and any repository license file. Run module development checks from `webui/`; Python
+installation remains governed by `pyproject.toml`.
+
+Das Repository stellt `@govoplan/workflow-webui` am Wurzelpfad für versionierte
+Git-Abhängigkeiten bereit. Version, öffentliche TypeScript-/CSS-Exporte und
+Peer-Anforderungen entsprechen `webui/package.json`; die Einstiegspfade liegen
+unter `webui/src`. Gemeinsame Core-/React-Peers stellt die einbindende Anwendung
+bereit. Die Fassade führt keine Entwicklungs- oder Installationsskripte aus.
+Entwicklungsprüfungen bleiben in `webui/`, die Python-Installation weiterhin in
+`pyproject.toml` definiert.
