# GerbilManager CI — Gitea Actions
# =================================
# STATUS: ENTWURF — inaktiv bis Julian Gitea Actions aktiviert.
# Aktivierung: Gitea -> Repository -> Einstellungen -> Actions -> "Actions aktivieren"
# Anschliessend: Gitea Actions Runner auf der NAS installieren (siehe docs/ops.md).
#
# Was dieser Workflow tut:
#   1. dotnet test (alle xUnit-Projekte)
#   2. npm test + npm run build (Frontend)
#   3. Docker-Images bauen und in die Gitea-Registry pushen
#
# Registry: truenas:13000  (internes Gitea Container Registry)
# Images:
#   truenas:13000/gulum/gerbilmanager-api:latest
#   truenas:13000/gulum/gerbilmanager-frontend:latest
