Icon Component Update Request

Please enhance the existing icon component with performance optimizations, accessibility improvements, design system integration, and advanced icon management features.

🎯 ICON UPDATE OBJECTIVES:

1. OPTIMIZE performance with improved SVG optimization, bundle efficiency, and rendering performance
2. ENHANCE accessibility with better ARIA support, semantic usage, and screen reader compatibility
3. INTEGRATE design system improvements with consistent theming, sizing, and visual harmony
4. ADD advanced features like dynamic icon loading, sprite optimization, and caching strategies
5. MAINTAIN backward compatibility while implementing modern icon management patterns

📋 ICON ENHANCEMENT METHODOLOGY:

STEP 1: Current Icon System Assessment

Performance Analysis:

• Bundle size impact: Analyze current icon library usage and bundle contribution
• Runtime performance: Review icon rendering efficiency and memory usage
• SVG optimization: Audit current SVG optimization levels and opportunities
• Loading strategy: Evaluate current icon loading patterns and caching

Accessibility Audit:

• ARIA compliance: Verify proper ARIA attribute usage and semantic structure
• Screen reader testing: Test icon announcements and navigation patterns
• Keyboard interaction: Review keyboard accessibility for interactive icons
• Color contrast: Ensure sufficient contrast across theme variations

Design System Review:

• Size consistency: Audit icon sizing across components and themes
• Visual alignment: Review icon alignment with text and other elements
• Theme compatibility: Test icons across light/dark themes and variants
• Brand consistency: Ensure icon style consistency with brand guidelines

STEP 2: Advanced SVG Optimization

Enhanced SVG Processing:

// Advanced SVG optimization with modern techniques
export class AdvancedSVGOptimizer {
  private optimizationCache = new Map()
  private performanceMetrics = new Map()

  async optimizeSVG(svgContent: string, options?: OptimizationOptions): Promise<OptimizedSVG> {
    const cacheKey = this.generateCacheKey(svgContent, options)
    
    if (this.optimizationCache.has(cacheKey)) {
      return this.optimizationCache.get(cacheKey)
    }

    const startTime = performance.now()
    
    const optimized = await this.performOptimization(svgContent, {
      removeComments: true,
      removeMetadata: true,
      removeEmptyElements: true,
      convertPathData: true,
      mergePaths: true,
      removeUselessStrokeAndFill: true,
      removeHiddenElements: true,
      ...options
    })

    const optimizationTime = performance.now() - startTime
    this.performanceMetrics.set(cacheKey, {
      originalSize: svgContent.length,
      optimizedSize: optimized.content.length,
      compressionRatio: optimized.content.length / svgContent.length,
      optimizationTime
    })

    this.optimizationCache.set(cacheKey, optimized)
    return optimized
  }

  private async performOptimization(svg: string, options: OptimizationOptions) {
    // Multi-pass optimization for maximum compression
    let content = svg

    // Pass 1: Remove unnecessary elements
    content = this.removeUnnecessaryElements(content)
    
    // Pass 2: Optimize paths and shapes
    content = this.optimizePaths(content)
    
    // Pass 3: Minify and clean up
    content = this.minifySVG(content)

    return {
      content,
      viewBox: this.extractViewBox(content),
      paths: this.extractPaths(content),
      metadata: this.extractMetadata(content)
    }
  }

  getPerformanceMetrics(cacheKey: string) {
    return this.performanceMetrics.get(cacheKey)
  }
}
