CSS Architecture

• All classes prefixed with .art- to avoid collisions
• All custom properties prefixed with --art- for namespacing
• Uses @layer css-art to avoid cascade conflicts with other libraries
• Colors use OKLCH format for perceptual uniformity
• Animations use @keyframes with art- prefixed names
