    How to verify a roll
    1. Before each spin the server commits to a 32-byte server_seed by publishing SHA-256(server_seed) above. The committed value cannot change for any spin that uses it.
    2. Each spin records the commit, client_seed, nonce and resulting HMAC-SHA-256(server_seed, client_seed:nonce:0).
    3. When you click Rotate seed, the server reveals the current server_seed. You can then verify SHA-256(server_seed) == commit and replay every spin to reproduce its slot result.
