Implementation Workflow

Identify Context: What's the product? Who's the audience?
Choose Style: Match visual style to brand/audience
Set Tokens: Define CSS custom properties
Build Components: Create reusable component library
Test Accessibility: Verify WCAG compliance
Optimize Performance: Check animation performance
Responsive Check: Test all breakpoints

Best Practices

Start with tokens - Define colors, spacing, typography first
Mobile-first - Design for smallest screens first
Test early - Accessibility testing from day one
Performance budget - Keep animations under 16ms/frame
Document everything - Create a living style guide
