I have an existing legacy PHP website that needs to be updated and modernized: Current site: https://www.puskaradio.net/ Design reference (target look & feel): https://jonh79-deepsite-project-6px9o.static.hf.space/index.html (this is an AI-generated example, can be used as inspiration and improved further with AI if useful) The current system is built with a simple PHP template structure, where a main body.php file acts as a wrapper and individual pages are loaded inside it using includes. The site contains multiple older subpages such as index.php, index2.php, etc. Example: https://www.puskaradio.net/index2.php?item_id=45647966 The most important pages are: Frontpage: https://www.puskaradio.net/ (index1.php) Review page: https://www.puskaradio.net/index2.php?item_id=45647966 The goal is to modernize the UI/UX, improve usability, and refresh the overall design while maintaining or improving the existing PHP structure and functionality.
