Learn/Build Tracks: From Concepts to Runnable Loops
Each lesson is split into Learn and Build: Learn defines boundaries and vocabulary, while Build turns calling patterns, I/O contracts, and error handling into reproducible steps. This makes “understanding” measurable by a runnable loop and surfaces real-world pitfalls early (auth, quotas, unstable outputs). Because lessons are modular, you can learn out of order by product pain while still applying the same engineering scaffold. For teams, the structure supports training and review: align principles first, then verify execution.
