## Matrix Dimensions
- **Style Variants**: ${styles}
- **Layout Variants**: ${layouts}
- **Pages/Components**: ${targets.join(', ')}
- **Total Prototypes**: ${styles * layouts * targets.length}
## Quick Start
1. **Interactive Comparison**: Open \`compare.html\` for side-by-side view with synchronized scrolling
2. **Browse Index**: Open \`index.html\` for a navigable list of all prototypes
3. **Individual Files**: Access specific prototypes directly (e.g., \`${targets[0]}-style-1-layout-1.html\`)
## File Naming Convention
\`\`\`
{page}-style-{s}-layout-{l}.html
\`\`\`
- **page**: Component/page name (${targets.join(', ')})
- **s**: Style variant number (1-${styles})
- **l**: Layout variant number (1-${layouts})
## Tips
- Use compare.html for quick visual comparison across all variants
- Synchronized scrolling helps identify consistency issues
- Check responsive behavior across different layout variants
