   Concept: "Field notes from a technical campus" — a coastal engineering
   ledger. Hairline rules, corner ticks and monospace coordinates borrow the
   vernacular of technical drawings, paired with a serif voice for the
   editorial/news content. Teal + brass, no stock photography — original
   line-art in its place.
