## 5. Engineering Philosophy

1. **Learn by Building**: True understanding comes from shipping functional, end-to-end applications rather than passive observation.
2. **Keep It Simple**: Write clean, self-documenting code with zero unnecessary dependencies.
3. **Design First**: Technical excellence must be paired with intuitive, accessible, and delighting user interfaces.
