jotoh.dev | Game rules as data

Store win and end conditions as a JSON AST ({op: "pointsAtLeast", n: 10} with all/any/not). A code registry resolves each op.
A world stores a frozen copy of its scenario and a rulesVersion. Changing a preset in code then does not change running worlds.
Each op lists its triggers (built, tileLost, …). Check only affected predicates on a tick. This keeps cost low at large scale.
Keep balance numbers in one constants package per scenario. No if scenario == X in the engine.
