Managing multiple packages in a single repository requires disciplined structure and reliable tooling.

## Pnpm Workspaces Setup

Here is a clean `pnpm-workspace.yaml` layout:

```yaml
packages:
  - 'apps/*'
  - 'packages/*'
  - '!**/test/**'
```

### Key Advantages

- **Deduplication**: Hard links save gigabytes of disk space across packages.
- **Strict Isolation**: Phantom dependencies are prevented by default.
- **Catalogs**: Centralize versions of shared dependencies in `pnpm-workspace.yaml`.
