Product Feature Demo Site

I need a clean, responsive demo site that lets prospects explore our product’s key features at a glance while weaving in real-world proof. The single most important goal is to showcase product features clearly and attractively; every section should steer visitors toward that understanding.

Customer testimonials will be the bridge between feature highlights and credibility. I’ll supply each testimonial as a website link, and the page should pull these into the design—whether that means embedding them as clickable quote cards, lightboxes, or another tasteful solution you propose—without breaking the site’s visual flow.

Core requirements
• Visually driven feature sections with concise copy blocks I can swap out later
• Testimonials displayed from the provided website links, styled to match the overall look
• Fully responsive layout and smooth, fast performance on desktop and mobile
• Code written in modern, standards-compliant HTML, CSS and JavaScript (a lightweight framework such as React or Vue is fine as long as setup remains simple)
• Hand-off of all source files plus a short read-me outlining build or deployment steps

Acceptance criteria
1. All primary product features are visible above the first scroll on common laptop resolutions.
2. Each testimonial link opens or expands without throwing console errors and matches the design palette.
3. Lighthouse performance score ≥90 on mobile.
4. Source compiles locally in one step and pushes cleanly to a standard hosting service (e.g., Netlify, Vercel).

Deliver the finished demo URL and repository when complete, and I’ll handle final hosting from there.
