Craft principle

Accessibility baseline.

Universal rules for the legal floor of accessibility plus the craft commitments that go beyond it. The active DESIGN.md decides brand appearance; this file decides which rules an artifact has to clear before it ships.

Other craft principles

Animation discipline Universal rules for when motion earns its place in a UI and what numbers constrain it. The active DESIGN.md decides brand-specific motion personality; this file decides whether motion should run at all and at what duration, easing, and accessibility floor.
Anti-AI-slop rules Concrete, checkable rules that distinguish "designed by a human who has shipped product" from "default LLM output." Several rules below are auto-enforced by the daemon's lint-artifact linter — failing an enforced rule is not a style preference, it is a regression. The rest are guidance for agents and reviewers and are flagged inline as "(guidance, not auto-checked)" so the contract with the linter stays honest.
Color Universal color rules applied on top of the active DESIGN.md. The design system supplies the palette tokens; this file enforces how to use them.
Editorial typography hierarchy Extends typography.md + typography-hierarchy.md. Defines hierarchy behavior for editorial surfaces: long-form articles, magazine layouts, digital guides, editorial landing pages, and blog posts.
