What problem does it solve? Teams building interfaces with spatial depth, isometric views, and layered elements often lack consistent, implementation-ready design rules, leading to inconsistent spacing, ambiguous component states, and accessibility gaps. ## Core Features & Use Cases - Design Token Foundations: Provides concrete color tokens (primary #00BD7D, success, warning, danger), typography scales (12/14/16/20/24/32 with Poppins, Oswald, JetBrains Mono), and spacing scales (4/8/12/16/24/32). - Component Rule Authoring: Defines component anatomy, variants, states (default, hover, focus-visible, active, disabled, loading, error), and responsive behavior for keyboard, pointer, and touch. - Accessibility & QA Gates: Enforces WCAG 2.2 AA requirements with testable acceptance criteria, anti-patterns, migration notes, and a code-review QA checklist. - Use Case: A designer-engineer pair building a dashboard with isometric 3D-like cards uses this Skill to generate token-anchored component rules and an accessibility checklist before implementation. ## Quick Start Ask the AI to generate design-system guidelines for a layered card component using the Perspective style with its defined color, typography, and spacing tokens.
