Roat Pkz - Provably Fair Blackjack Verifier

Images are referenced by their imageValue (1‑52) matching Roat Pkz assets. Deck count is fixed at 8.

Only the first 30 cards of the deck are displayed; the rest are omitted as they’re not relevant. Adjust this by changing renderFirstN(deck, 30);

This HTML page is fully self-contained and works entirely offline - it never communicates with any external server.

How the shuffle works: We derive a combined seed by concatenating server_seed, client_seed, and nonce, hashing that string with SHA‑256, and feeding the digest into a deterministic PRNG that shuffles a fixed 8‑deck shoe. Anyone with the three inputs can reproduce the exact same deck order-provably fair.
