# 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.
