"""
Sets a background image for the Streamlit application with optional opacity control.
This function applies a background image to the entire Streamlit app (`.stApp` container)
using CSS with a linear gradient overlay. The overlay enhances text readability by adding
a semi-transparent dark layer over the image.
Args:
file_path (str): The file path of the background image (supports PNG, JPG, etc.).
opacity (float, optional): The opacity level of the dark overlay.
Values range from 0 (fully transparent) to 1 (fully opaque).
Default is 0.5, providing balanced readability and background visibility.
Example Usage:
```python
set_bg_image("src/frontend/images/health_care_banner.png", opacity=0.6)
```
Notes:
- Ensure the provided `file_path` is accessible and the image is properly encoded in base64 format.
- For optimal results, use high-resolution images with suitable contrast to enhance readability.
