How it works

When you run the app, Flask starts a local server on
http://127.0.0.1:5000.

The app exposes several API endpoints:

Method	Endpoint	Description
GET	/ping	Health check
GET	/notes	List all notes
POST	/notes	Create a new note
PUT	/notes/<id>	Update a note
DELETE	/notes/<id>	Delete a note

Each note has:

• id — unique identifier
• title — note title (required)
• content — optional text content
• created_at — timestamp
• updated_at — timestamp
