+# Architecture
+
+## Current Baseline
+
+- `client/` hosts the React application and game shell.
+- `server/` hosts the Express API, production static asset serving, and future persistence services.
+- `docker/` contains a single-container production build and local compose entrypoint.
+
+## Immediate Direction
+
+- M0 keeps the game scene intentionally simple.
+- M1 replaces the placeholder canvas renderer with a Matter.js-driven absorber loop.
+- Persistence is currently in-memory and will move to SQLite during M3.
+- Production packaging now uses one container that serves both the API and built client from Express.
