Boxy

Boxy is a zero-radius design system that enforces a strict set of axioms for UI design, focused on interfaces with square corners, hairline structure, engineered detail, and a rationed neutral palette. It includes a linter called boxy-check that parses front-end code to ensure adherence to these design rules, failing builds if violations occur. The system is designed for AI coding agents to use for consistent, accessible, and structured interface generation.
