What problem does it solve? Teams building editorial or long-form reading interfaces often lack consistent, token-driven design rules, leading to inconsistent spacing, low-contrast text, and ad-hoc component styling. This Skill turns the Terracotta design foundations into concrete, testable guidance for engineers and designers. ## Core Features & Use Cases - Token-Driven Foundations: Defines the Terracotta palette (primary #C56A3C, cream surfaces), DM Serif Display typography scale, and 4/8/12/16/24/32 spacing rhythm as semantic tokens. - Component Rule Authoring: Produces component anatomy, variants, states (hover, focus-visible, disabled, loading, error), and responsive behavior rules. - Accessibility Acceptance Criteria: Anchors every rule to WCAG 2.2 AA requirements, keyboard interaction, and testable QA checklists. - Use Case: When building a blog or storytelling site, ask for button, card, and typography guidelines and receive opinionated rules with do/don't examples, anti-patterns, and a code-review-ready QA checklist. ## Quick Start Generate Terracotta design-system guidelines for the button and card components in my editorial blog layout.
