Adds gzip compression and ETag support for better caching
Implements response compression and ETag headers to optimize asset delivery and enable client-side caching, reducing bandwidth usage and improving load times. Enhances code block styling and syntax highlighting for documentation clarity. Adds gzip compression, ETag caching, and code block styling Improves server performance by implementing gzip response compression and ETag-based caching for static and dynamic content, reducing bandwidth and enabling efficient client-side caching. Enhances documentation clarity with improved code block styling and syntax highlighting support.
