# Build: "Cambium" — an online school for designing with living systems

## 0. Brief

A long, light editorial landing for Cambium, a fictional online school where designers, engineers and growers learn to build with biology, data and machines. A moss-topped soil core floats in sage mist while a coral-red crown of branches (coral, roots and neurons at once) grows live from its moss, thickens, answers the pointer and sheds petals; the same growth writes "Cambium" in the loader and the footer. Serif type, small mono tags, hairlines, sharp photographs; besides them, colour lives only in living things and actions (one coral). Signature moments: a moss-covered 1970s television playing chapter one of each program, and a tree cross-section that grows ring by ring with scroll.

The full prompt unlocks at launch.
