Das Submodul zeigte auf GitHub, der eingetragene Stand 028c652 lag aber nur lokal vor: GitHub-Master ac39682 plus Showcase mit Figuren und launch.json. Frische Klone konnten den Controller deshalb nicht laden. Jetzt liegt dieser Stand als normaler Ordner im Repo, ohne Verweis auf GitHub. dist/ und node_modules/ im Controller bleiben ignoriert und werden wie bisher lokal gebaut.
