What it is
A from-scratch shared engine — not a fork of any one game. Each game is a thin rule pack; the table UI, renderers, multiplayer, economy, and operations are shared. Below, the same modules render real game frames, run a deterministic match, and stress a simulated server — all self-contained, all reproducible.
