+# Intentionally empty config file for test-server startup.
+#
+# Used as `--config tests/common/empty.env` by the Playwright
+# webServer scripts (`tests/e2e/start-server*.sh`). Two properties
+# it gives us that a bare `cargo run` doesn't:
+#
+#   1. Loading an empty file overrides nothing, so every var
+#      Playwright places in the child process env (SERVER_PORT,
+#      STORAGE_PATH, RUST_LOG, OPAQUE_MODE, DPOP_MODE, whatever
+#      per-suite overrides land here) reaches the server intact.
+#
+#   2. Passing `--config <anything>` in main.rs takes the
+#      `Some(path)` branch and skips the fallback
+#      `dotenvy::dotenv()` probe of `$CWD/.env`. Without this a
+#      developer's local `.env` (typical:
+#      `OXICLOUD_METRICS_LISTEN=127.0.0.1:9090`) leaks into the
+#      test server via CWD auto-load and clashes with whatever
+#      the dev is already running.
+#
+# Hurl API tests use `tests/common/server.env` for --config
+# instead — they source it in shell first, so file-wins doesn't
+# matter there. Only Playwright needs the empty-file trick
+# because it applies per-suite env overrides that would otherwise
+# be clobbered by server.env's shared values.
