/* ==========================================================================
   Project Cards — filterable grid, concise cards with an image slot (real
   photo or a clearly labeled placeholder), market/location tags, owner,
   a short scope preview, and service tags. Built by
   js/modules/project-cards.js (Expertise grid, with filters + Load More)
   and js/modules/featured-projects.js (homepage curated teaser row) via the
   shared js/modules/project-card.js renderer, so both look identical.
