"""
Advanced URL & Text Processing Suite
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A sophisticated, enterprise-grade toolkit for URL processing, file manipulation, and QR operations.
Designed with performance, scalability, and reliability in mind.

Key Features:
    - Intelligent URL Processing with adaptive rate limiting
    - Universal File Processing with smart content extraction
    - Advanced QR Code operations with custom styling
    - Modern, responsive UI with real-time feedback
    - Enterprise-grade security and performance

Example:
    >>> from urld import URLProcessor, FileProcessor, QRProcessor
    >>> url_proc = URLProcessor(request_delay=1.0)
    >>> result = url_proc.process_urls(['https://example.com'])
    >>> print(result)
