The demo runs in your browser.

No accounts, no Worker connection — this page simulates an 8-player, 9-hole stroke-play tournament with the admin console, a player phone, an attester tablet, and the public leaderboard, all rendering off shared state. Tap a hole on the player panel, attest from the attester panel, watch the leaderboard reorder. Reset wipes it all.

Heads up: the demo writes to memory only. The production surfaces connect to a per-tournament Durable Object via WebSocket and persist to a per-tournament Sheet. Run a real one →
