# Build: "DATUM" — a contractor's site from open ground to a finished building, told in one scroll
## 0. Brief
A fictional contractor for concrete-frame buildings. The page opens on its finished riverside building at dusk; where the pointer passes, the same frame shows day one (bare yard, one excavator under a green work light). Scrolling opens day one, rises to a night satellite map of a conceptual city that zooms through logistics to the plot, then a fixed rooftop site camera builds the building with the scroll. Interludes, handover, projects, company and a footer where the name rises from the ground close it. Industrial, editorial, calm; one green accent; formwork geometry in every component.The full prompt unlocks at launch.
