+# CI for shopdb-flask on GitHub Actions.
+#
+# Mirrors the internal CI pipeline. Four jobs on push + pull_request:
+#   backend          - pytest (SQLite via TestingConfig, no DB service needed)
+#   naming           - the CONTRIBUTING.md naming/style gate
+#   frontend         - vitest + Vue build
+#   migrations-mysql - the REAL multi-site deploy path: fresh flask db upgrade
+#                      + every plugin's chain on utf8mb4 MySQL 8, idempotent on
+#                      a second run. The pytest suite only exercises SQLite
+#                      create_all(), so this is what catches an Alembic
+#                      regression on MySQL before it ships.
