What “Use in my project” copies

Download https://faundr.dev/resources/design-md/notion/DESIGN.md and save it as design.md at the project root. It's a design guide inspired by Notion, measured from their site: follow its colors, fonts, corners and components on every screen you create or change. Where it calls for a paid font, use the free alternative the file names.

A design.md only works if someone checks it.

Faundr reads your design.md and checks every screen your AI touches: colors off the guide, rebuilt components, clipped menus, broken mobile.
