This is a complete Tailwind-based design system that enforces classic Swiss International Style: grotesque typography (IBM Plex Sans with careful fallbacks), stone color palette, opacity-based hierarchy instead of color variations, and strict grid discipline. It's opinionated in the best way: one accent color per project, 60-character line lengths for body text, 8px spacing increments, and mobile-first responsive rules baked in. The typography section alone is worth it, with proper ellipses, curly quotes, tabular numerals, and text balancing. If you've ever wanted to make a UI look clean without overthinking it, or if terms like "grotesque fonts" and "generous whitespace" appeal to you, this gives you a complete playbook. It's not minimalist for minimalism's sake, it's structured restraint with clear rules.
