SuccessfullSites/Agency-Website ? reverse-engineered prompt

Build me a clean, modern responsive agency website template that I can use as a starting point for a community or small business site.

It should be made with plain HTML, CSS, Bootstrap 5, and a little JavaScript, and it needs to look good on mobile, tablet, and desktop. I want the page to feel polished and easy to edit, with reusable sections in a components folder so I can swap things in and out without touching everything.

Please include a strong hero section, navigation, service or feature sections, about content, portfolio or work showcase, testimonials, and a contact area, plus any nice small interactions that make it feel alive. Keep the styling modern and simple, and make sure the whole thing is easy to open locally in index.html and customize by editing the HTML and CSS.

If you need any current Bootstrap or browser details, look them up online first.
