+# The OIDC suite's Step 4 + Step 9 walk the full redirect chain and assert
+# they land on `/login?oidc_code=…` with HTTP 200 — the production contract,
+# where the container ships `static-dist/login.html`. Without that bundle
+# `resolve_static_path` falls back to `OXICLOUD_STATIC_PATH=./static`, which
+# was removed in commit 54639d46 — so ServeDir 404s the route and Step 4
+# fails. Build here so local + CI both exercise the production layout.
