You are generating a design system for a minimalist, dark-themed manifesto website. The palette is strictly monochrome: pure black (#000000) background with white (#FFFFFF) primary text and a muted gray (#6F6F6F) for secondary elements like the call-to-action button. The typography is Roboto, a humanist-sans font, used exclusively at font-weight 400 across all elements. The layout is centered and vertically stacked. Key dos: use high contrast, maintain generous vertical spacing, keep the interface minimal. Key donts: never introduce a bright accent color, never use decorative patterns or shadows, never use multiple font weights. The voice is authoritative and visionary. This system should feel premium, focused, and deliberate.
