Chess Jev Web

A Next.js chess app whose API route forwards each position to the System One endpoint as one typed choice question per move.

What it does

A JEV_MOCK flag swaps the API for a random picker so the interface can be styled without spending tokens — the mock returns confidence 1, which the UI politely displays like any other verdict.
