How the leaderboard works
Pick any of the 14 tests, then switch between Global, Today and This Week views. The ranked rows are clearly labelled demo data so you can see the format while no global server exists yet. Below them, your own local best for the selected test appears automatically from your browser storage — that row is real, and beating it moves you up your personal board even though the demo rows stay fixed.
