+# Prometheus /metrics exporter (opt-in via OXICLOUD_METRICS_LISTEN).
+# `metrics` is the abstract counter API — `counter!(name, "k" => v).increment(1)`
+# — and is a no-op when no recorder is installed (unset env var). The
+# `metrics-exporter-prometheus` crate registers a recorder and renders the
+# text-format /metrics scrape. Both re-export ordered voted versions that
+# agree on their `metrics-util` transitive dep — pin as a pair when
+# bumping either side.
