We’re refreshing our corporate website to better express precision and modernity. The experience should feel minimal, grid‑first, and typographically disciplined (one sans‑serif, clear hierarchy, generous whitespace). Marketing must be able to update content without engineering help, so use a static site powered by a headless CMS.

Key areas:
- Case Studies: a browsable list with category filters and detail pages; filters must be shareable via URL.
- Services: reusable content blocks that can be cross‑linked across pages.
- About Us: a timeline of company milestones.

Please propose the information architecture, content model, and component library, then build the site with Next.js and Tailwind (or an equivalent static setup) integrated with a CMS like Contentful. Prioritize performance, SEO, accessibility, and responsive behavior. Include image optimization, metadata/OG tags, and an editorial preview mode so the team can review changes before publishing.
