What is this?
Capstone: ship a tiny authenticated notes app — register/login, JWT, Mongoose Note model, React list/create/delete, protected routes.
Why should you care?
A vertical slice beats unfinished Kafka diagrams.

What happened?
- Integrate prior lessons.
- Deploy optional; local demo is enough for learning.
Practice next
- Finish API CRUD with auth.
- Build login + notes UI.
- Delete a note end-to-end.
- Add pagination.
- Add Docker Compose later.
Remember
Capstone = auth + CRUD slice. API and UI both required. Keep scope tiny.
