## Description

Angular Universal is a server-side rendering framework and static site generator for Angular applications. It provides the core engines and tools necessary to generate HTML on a server or during the build process to improve initial load performance and search engine optimization.

The project enables both dynamic server-side rendering for on-demand HTML generation and build-time prerendering to create static files for predefined routes. It features a hydration engine that transfers server-side state and cached HTTP responses to the client, preventing the browser from duplicating network requests during application startup.

The framework covers broader web delivery optimizations, including isomorphic code execution and the injection of inline styles to comply with content security policies. These capabilities ensure that the same logic runs across the server and browser while maintaining consistent application state and visual stability.
