The landing page will utilize a "parallax" interaction model, providing layered depth via scroll. Decorative elements like cricket balls and bats will translate at different speeds, creating a dynamic and engaging first impression. Internal pages will adopt a "static" model to ensure clarity and readability, focusing on data-heavy content like scores and statistics.
