 * The `route` label is the route *template* (`/teams/:id`), never the URL that arrived. Using the
 * raw path would give a distinct time series per team id, per service name, per resource id — the
 * classic way a metrics endpoint quietly becomes the most expensive thing in a Prometheus
 * instance. A request that matched no route is labelled `__unmatched__` for the same reason:
 * scanners produce unbounded 404 paths, and they must not each mint a series.
