What problem does it solve? Building interfaces that match Apple's visual identity requires exact design tokens — colors, typography scales, spacing, and component rules — that are tedious to research and easy to get wrong. This Skill provides the complete Apple design system specification so generated UI matches Apple's look and feel. ## Core Features & Use Cases - Complete Design Tokens: Exact color values (Apple Blue #0071e3, #f5f5f7, #1d1d1f), SF Pro typography hierarchy, spacing scale, border radius, and shadow specifications. - Component Styling Rules: Detailed specs for buttons, pill CTAs, cards, translucent glass navigation, forms, and product hero modules. - Light & Dark Previews: Bundled HTML preview files (preview.html, preview-dark.html) showing the design system implemented in both themes for visual verification. - Use Case: Ask for a landing page styled like Apple's website and receive a hero section with a 56px SF Pro Display headline, alternating black and light-gray sections, and 980px pill CTAs. ## Quick Start Use the design-apple skill to create a product landing page styled like apple.com with a hero section and product cards.
