Deep-dive path

1. Read the matching roadmap lesson first and implement the code locally.
2. Open the official documentation for the feature you are using.
3. Check one tool or framework guide only after you understand the manual approach.
4. Write one note about a trade-off, limitation, or integration detail you discovered.

Practice

Pick one Kotlin topic, read the official documentation, then implement a small local example and write one short review of what the docs clarified.
