The prompt

Excerpt / 606 lines in the full prompt

# Build: "Isohel" — a SaaS landing page where a band of refracted light crosses a dawn landscape

## 0. Brief

Isohel is a fictional SaaS for leadership teams: it connects finance, revenue and people systems, writes a weekly brief, forecasts, drafts board packs and logs decisions. A template: every word lives in one content module, every colour in CSS tokens. The page is one day of light: dawn in the hero (a WebGL band of refracted light over a pale tundra), morning scenes behind the product, golden hour behind integrations, a strip of noon sky, alpenglow in the closing, a blue-hour footer. Quiet and editorial: a thin serif, a plain sans, and one saturated thing (the light).

The full prompt unlocks at launch.
