### 🌟 Key Files and Their Roles

- **`app.py`**: Entry point initializing FastAPI app and routes.
- **`Procfile`**: Tells Railway (or similar platforms) how to run the program.
- **`requirements.txt`**: Tracks all Python dependencies for the project.
- **`__init__.py`**: Package initializer for the root module and submodules.
- **`features/text_classifier/`**
  - **`controller.py`**: Handles logic between routes and the model.
  - **`inferencer.py`**: Runs inference and returns predictions as well as file system 
  utilities.
- **`features/NP/`**
  - **`controller.py`**: Handles logic between routes and the model.
  - **`inferencer.py`**: Runs inference and returns predictions as well as file system 
  utilities.
  - **`model_loader.py`**: Loads the ML model and tokenizer.
  - **`preprocess.py`**: Prepares input text for the model.
  - **`routes.py`**: Defines API routes for text classification.
