Thoroughly analyze and replicate [insert URL here]. Autonomously identify and implement all essential elements, including: Core functionalities and features User interface and experience Backend systems and data structures API integrations and external services Security measures and authentication Performance optimizations Cross-platform compatibility Unique characteristics and selling points Regulatory compliance features Accessibility components Generate a fully functional web app that mirrors the original site's capabilities as accurately as possible, adhering to modern web development best practices. Implement all necessary technologies to ensure complete functionality and user experience replication. For any components or integrations that cannot be directly replicated, automatically devise and implement the closest possible alternative solution that maintains the core functionality and user experience. This includes creating built-in alternatives for external services, developing simplified versions of complex features, or finding creative workarounds for proprietary elements. Ensure that these alternatives align with the overall purpose and functionality of the original application.
