Build me a polished case study portfolio site for a digital agency that feels modern and premium, but is still simple to update. I want the homepage to showcase projects as full case studies, not just pretty thumbnails, with clear sections for Challenge, Solution, and Results, plus measurable metrics, screenshots, and links to the live site or demo. Include filters so visitors can sort by industry, service, technology, and search by name, and make a featured section at the top for the best work.

Each project should open in a clean modal or detail view with keyboard navigation, previous and next controls, and a lightbox for gallery images. It should also support shareable links to specific projects. Make it fully responsive, fast to load, and easy to host anywhere with no backend. Keep content editable from one JSON file so the agency can add or update projects without touching the layout.
