## 🎨 Key Features (Brand-Aligned Implementation)

### 1. Ultra-Minimalist Design System
```typescript
// CHORUS 8-Color System Implementation
const heroColors = {
  primary: 'text-carbon-950 dark:text-paper-400',
  secondary: 'text-mulberry-950 dark:text-mulberry-200',
  accent: 'text-walnut-900 dark:text-walnut-400',
  neutral: 'text-nickel-400',
  background: 'bg-carbon-950', // Dark mode default
};

// Ultra-clean typography
const typography = {
  headline: 'font-logo text-6xl font-regular tracking-wide',
  tagline: 'font-sans text-xl font-light',
  body: 'font-sans text-base leading-relaxed',
};
```

### 2. Three.js Möbius Ring Integration
```typescript
// Logo with accessibility adaptations
const ChorusLogo = ({ accessibilityTheme = 'default' }) => {
  useEffect(() => {
    // Initialize Three.js Möbius Ring
    // Apply accessibility theme materials
    updateLogoMaterials(accessibilityTheme);
  }, [accessibilityTheme]);
  
  return (
    <canvas 
      className="chorus-logo aspect-square"
      data-accessibility-aware="true"
    />
  );
};
```

### 3. CHORUS Accessibility System
```typescript
// Comprehensive accessibility implementation
const AccessibilityProvider = ({ children }) => {
  const [accessibilityTheme, setAccessibilityTheme] = useState('default');
  
  const themes = {
    protanopia: { logoMaterial: '#1e40af', colorAdjustments: 'blue-focus' },
    deuteranopia: { logoMaterial: '#6b21a8', colorAdjustments: 'purple-focus' },
    tritanopia: { logoMaterial: '#991b1b', colorAdjustments: 'red-focus' },
    achromatopsia: { logoMaterial: '#374151', colorAdjustments: 'grayscale' },
  };
  
  return (
    <div data-accessibility={accessibilityTheme}>
      {/* Accessibility-aware component tree */}
    </div>
  );
};
```

### 4. Performance & SEO Optimizations
```typescript
// Ultra-minimalist performance strategy
const HeroSection = () => {
  const reducedMotion = useReducedMotion();
  
  return (
    <section 
      className="min-h-screen bg-carbon-950 text-white"
      aria-label="CHORUS Services introduction"
    >
      {/* Three.js logo with GPU acceleration */}
      <ChorusLogo 
        size={128}
        interactive={!reducedMotion}
        accessibilityTheme={accessibilityTheme}
      />
      
      {/* Ultra-clean typography */}
      <h1 className="font-logo text-6xl font-regular mb-chorus-lg">
        CHORUS
      </h1>
      
      {/* Semantic tagline */}
      <p className="font-sans text-xl font-light mb-chorus-xl">
        Distributed AI Orchestration Without the Hallucinations
      </p>
    </section>
  );
};
```

## 🚀 Ultra-Minimalist Animation Strategy

### Page Load Sequence (Reduced Complexity)
1. **Three.js logo initialization** - Möbius Ring renders (200ms)
2. **Typography fade-in** - Clean, semantic headline appearance (400ms)
3. **Content reveal** - Tagline and navigation (600ms)
4. **Accessibility ready** - All themes loaded and available (800ms)
5. **Interactive state** - Logo interaction enabled (1000ms)

### Accessibility-Aware Animations
```typescript
// Respect user preferences
const animationConfig = {
  duration: reducedMotion ? 0 : 200,
  easing: 'ease-out',
  respectMotionPreferences: true,
};

// Three.js logo with motion control
const logoAnimation = {
  rotation: reducedMotion ? 0 : 0.01,
  interaction: !reducedMotion,
  materialTransitions: 200, // Always allow material changes for accessibility
};
```

## 🎯 CHORUS Ultra-Minimalist Design Principles

### Visual Design (Brand-Compliant)
- **Typography Hierarchy** - Exo for logo, Inter Tight for content, Inconsolata for code
- **CHORUS Spacing** - 8px, 16px, 32px, 64px, 128px system (chorus-sm to chorus-xxl)
- **Color Semantic Tokens** - 8-color system with semantic meaning
- **Dark Mode Default** - Carbon black (#000000) primary background
- **Three.js Integration** - Interactive Möbius Ring with accessibility themes

### Interaction Design (Accessibility-First)
```typescript
const interactionStates = {
  hover: 'transition-colors duration-200 ease-out',
  focus: 'ring-2 ring-offset-2 ring-chorus-accent',
  active: 'transform scale-95 transition-transform duration-100',
  disabled: 'opacity-50 cursor-not-allowed',
};

// Keyboard navigation support
const keyboardHandler = (event) => {
  if (event.key === 'Tab') {
    // Ensure visible focus indicators
    document.body.classList.add('keyboard-navigation');
  }
};
```

## 🔧 Performance Metrics (Updated Targets)

### Core Web Vitals Optimization
- **LCP Target**: <2.5s (First Möbius Ring render)
- **FID Target**: <100ms (Logo interaction responsiveness)
- **CLS Target**: <0.1 (Stable layout with Three.js canvas)
- **Bundle Size**: <500KB initial load with Tailwind CSS optimization
- **Lighthouse Score**: 95+ across Performance, Accessibility, Best Practices, SEO

### CHORUS Accessibility Compliance
```typescript
// Complete accessibility implementation
const accessibilityFeatures = {
  wcag: '2.1 AA compliant',
  screenReaders: 'Semantic HTML with ARIA labels',
  keyboard: 'Full tab navigation support',
  colorVision: 'Four accessibility theme adaptations',
  motion: 'prefers-reduced-motion respected',
  contrast: 'WCAG AA contrast ratios maintained',
  logoAdaptation: 'Three.js materials adapt to vision conditions'
};

// SEO optimization for ultra-minimalist design
const seoStrategy = {
  structuredData: 'JSON-LD for software application',
  semanticHTML: 'H1, H2, section, article hierarchy',
  metaDescription: 'Concise, keyword-optimized descriptions',
  openGraph: 'Optimized social sharing',
