## Running Tests

```bash
# Go engine tests
go test ./engine/... -v

# Web build verification
cd web && npm run build
```

## Building CLI Tools

```bash
go build ./cmd/acb-local
go build ./cmd/acb-mapgen
```

## Running a Match

./acb-local -seed 42 -max-turns 100 -output replay.json -verbose
```

## Viewing a Replay

```bash
cd web
npm run dev
# Standalone viewer: http://localhost:3000/index.html
# Full SPA: http://localhost:3000/app.html (then go to #/replay)
```
