What it is
Prompt a decision model to play Reversi, then compare with a code twin.
What it does: Computes board features, asks hosted Jev which legal move fits the POLICY, and logs matches in a desktop GUI.
Why it belongs in the showcase: Clear TypeSafe SDK Choice usage on structured game state.
Caveats: Toy domain; verify against current SDK docs.
