    Only the Shopify-hosted merchandise store publishes a /.well-known/ discovery surface. The
    league's own web and stats hosts return 404 for every well-known path probed, including
    security.txt. No agent card was found at either the canonical /.well-known/agent-card.json or
    the legacy /.well-known/agent.json on any host.
