Build me a clean, modern website for CSF that feels polished and easy to use on phone and desktop.

I want the site to make it simple for visitors to understand what CSF is, find the main information quickly, and contact or get involved without any confusion. Keep the design friendly and professional, with clear sections, readable text, and a layout that works well on different screen sizes. Make it feel like a real community or organization site, not a generic template.

Use the existing project structure if there is already something started, and fill in anything missing so the site looks complete. If you need to check current best practices or a small detail online, go ahead. Please make it look finished, with good spacing, consistent colors, and a simple navigation that makes sense.
