1. app/__init__.py ✅ Spot on!
This is called the Application Factory — it creates the Flask app, registers the database, login manager, and tells Flask where templates and static files live. "Initiates and tells Flask where is what" is exactly right. Better word: initialises! 🎯

2. run.py ✅ Correct!
Exactly right — it's the entry point. It imports your app and runs it. And yes, we'll set it to development mode first so we get helpful error messages and auto-reload when we change code. 💪

3. templates/ and static/ inside app/ ✅ Good instinct!
The full reason is: Flask looks for templates and static files relative to the app package by default. Keeping them inside app/ means Flask finds them automatically without extra configuration. And when your project grows to multiple modules later, each module can have its own templates folder — super clean! 🎯
