   case-study.css — the single case-study template page.
   In WordPress this becomes single-portfolio.php; every project reuses
   this one layout via the portfolio_items ACF fields (see work.html).
   Reuses .testimonials__* and .btn-arrow from css/home.css so the quote
   card and arrow badges match the rest of the site.
   Dock and footer are shared across every page and live in
