{"agent":"codex","input":"Build an admin page that shows live listener counts per profile, using LiveBeatsWeb.Presence and the topic active_profiles, available only to admins as LiveBeats.Accounts.admin?/1 defines them (the :admin_emails config, not :admin_usernames). Add an on_mount hook beside the ones in lib/live_beats_web/controllers/user_auth.ex and a live route in lib/live_beats_web/router.ex. Follow the existing layout. Add tests in the ConnCase style of test/live_beats_web/live/profile_live_test.exs, including the non-admin redirect. Run mix test. Take screenshots in the browser at the dev server on port 4000. Open a pull request. Ask before adding any dependency.","resources":[{"url":"https://github.com/your-org/your-app"}]}
