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.
