 ---
 ## Accessibility Features (WCAG 2.1 AA)
 ### Semantic HTML
 - Proper roles: `role="button"`, `role="progressbar"`, `role="alert"`
 - ARIA attributes: `aria-label`, `aria-expanded`, `aria-disabled`, `aria-valuenow`
 - Heading hierarchy maintained
 ### Keyboard Navigation
 - All interactive elements keyboard accessible

 ---
 ## Responsive Design
 All components are mobile-first with 4 breakpoints:
 **Base (< 768px - Mobile):**

 - All components maintain max-width constraints
 ---
 ## Performance Optimizations
 1. **Next.js Image Component**
   - Automatic optimization
   - Lazy loading
   - Proper sizing attributes
 2. **Memory Management**
   - Preview URLs revoked on unmount
   - Event listeners cleaned up
   - Timers cleared properly
 3. **Efficient Rendering**
   - Minimal re-renders
   - CSS transitions over JS animations
   - Optimized state updates
 ---
 ## Integration Guide
 ### Step 1: Import Components
 ```tsx
 import {
  FileDropZone,
  UploadProgressBar,
  UploadResultCard,
  UploadResult,
 } from '@/components/demo/upload';
 ```
 ### Step 2: State Management
 ```tsx
 const [file, setFile] = useState<File | null>(null);
 const [uploading, setUploading] = useState(false);
 const [progress, setProgress] = useState(0);
 const [status, setStatus] = useState<'uploading' | 'processing' | 'success' | 'error'>('uploading');
 const [results, setResults] = useState<UploadResult[]>([]);
 const [zoomedImage, setZoomedImage] = useState<string | null>(null);
 ```
 ### Step 3: Upload Handler
 ```tsx
 const handleFileSelect = async (selectedFile: File) => {
  setUploading(true);
  setProgress(0);
  setStatus('uploading');
  const startTime = Date.now();
  try {
    // Simulate progress (replace with real upload)
    const formData = new FormData();
    formData.append('file', selectedFile);
    const response = await fetch('/api/upload', {
      method: 'POST',
      headers: { 'X-API-Key': apiKey },
      body: formData,
    });
    const data = await response.json();
    setStatus('success');
    // Create result
    const newResult: UploadResult = {
      id: Date.now().toString(),
      timestamp: new Date(),
      originalFile: {
        name: selectedFile.name,
        size: selectedFile.size,
        type: selectedFile.type,
      },
      uploadedImage: {
        url: data.url,
        width: data.width,
        height: data.height,
      },
      durationMs: Date.now() - startTime,
    };
    setResults(prev => [newResult, ...prev]);
  } catch (error) {
    setStatus('error');
  } finally {
    setUploading(false);
  }
 };
 ```
 ### Step 4: Render Components
 ```tsx
 <div className="max-w-7xl mx-auto px-6 py-12">
  {/* Upload */}
  <FileDropZone onFileSelect={handleFileSelect} disabled={uploading} />
  {/* Progress */}
  {uploading && <UploadProgressBar progress={progress} status={status} />}
  {/* Results */}
  {results.map(result => (
    <UploadResultCard
      key={result.id}
      result={result}
      onZoom={setZoomedImage}
      onDownload={handleDownload}
    />
  ))}
  {/* Zoom Modal */}
  {zoomedImage && <div>...</div>}
 </div>
 ```

 ```tsx
 import { FileDropZone } from '@/components/demo/upload';
 <FileDropZone
  onFileSelect={(file) => handleFile(file)}
  accept="image/jpeg,image/png,image/webp,image/gif"
  maxSizeMB={5}
  disabled={uploading}
 />
 ```
 **Props:**
 - `onFileSelect: (file: File) => void` - Callback when valid file selected
 - `accept?: string` - Accepted file types (default: image types)
 - `maxSizeMB?: number` - Max file size in MB (default: 5)
 - `disabled?: boolean` - Disable interaction
 **States:**
 - Empty: Default state with upload icon
 - Drag over: Highlighted when dragging file over
 - File selected: Shows preview thumbnail and file info
 - Error: Displays validation error message

  progress={uploadProgress}
  status={uploadStatus}
  error={errorMessage}
 />
 ```
 **Props:**
 - `progress: number` - Progress percentage (0-100)
 - `status: 'uploading' | 'processing' | 'success' | 'error'` - Current status
 - `error?: string` - Error message (only shown when status='error')
 **Status Colors:**
 - `uploading`: Amber gradient (from-amber-600 to-orange-600)
 - `processing`: Purple gradient (from-purple-600 to-cyan-600)
 - `success`: Green gradient (from-green-600 to-emerald-600)

 ## Integration Example
 Here's a complete example of how to use all three components together:
 ```tsx
 'use client';
 import { useState } from 'react';
 import {
  FileDropZone,
  UploadProgressBar,
  UploadResultCard,
  UploadResult,
 } from '@/components/demo/upload';
 export default function UploadDemoPage() {
  const [file, setFile] = useState<File | null>(null);
  const [uploading, setUploading] = useState(false);
  const [progress, setProgress] = useState(0);
  const [status, setStatus] = useState<'uploading' | 'processing' | 'success' | 'error'>('uploading');
  const [results, setResults] = useState<UploadResult[]>([]);
  const [zoomedImage, setZoomedImage] = useState<string | null>(null);
  const handleFileSelect = async (selectedFile: File) => {
    setFile(selectedFile);
    setUploading(true);
    setProgress(0);
    setStatus('uploading');
    const startTime = Date.now();
    try {
      // Simulate upload progress
      for (let i = 0; i <= 100; i += 10) {
        await new Promise(resolve => setTimeout(resolve, 100));
        setProgress(i);
      }
      setStatus('processing');
      // Call your upload API here
      const formData = new FormData();
      formData.append('file', selectedFile);
      const response = await fetch('/api/upload', {
        method: 'POST',
        headers: { 'X-API-Key': apiKey },
        body: formData,
      });
      const data = await response.json();
      setStatus('success');
      setProgress(100);
      // Add result
      const newResult: UploadResult = {
        id: Date.now().toString(),
        timestamp: new Date(),
        originalFile: {
          name: selectedFile.name,
          size: selectedFile.size,
          type: selectedFile.type,
        },
        uploadedImage: {
          url: data.url,
          width: data.width,
          height: data.height,
        },
        durationMs: Date.now() - startTime,
      };
      setResults(prev => [newResult, ...prev]);
    } catch (error) {
      setStatus('error');
    } finally {
      setTimeout(() => setUploading(false), 2000);
    }
  };
  const handleDownload = async (url: string, filename: string) => {
    const response = await fetch(url);
    const blob = await response.blob();
    const blobUrl = URL.createObjectURL(blob);
    const link = document.createElement('a');
    link.href = blobUrl;
    link.download = filename;
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
    URL.revokeObjectURL(blobUrl);
  };
  return (
    <div className="max-w-7xl mx-auto px-6 py-12">
      {/* Upload Section */}
      <section className="mb-8">

          />
        </div>
      )}
    </div>
  );
 }
 ```

 - lg: >= 1024px (desktop)
 **Responsive Features:**
 - FileDropZone: Adapts layout for mobile/desktop
 - UploadResultCard: Stacks vertically on mobile, horizontal on desktop
 - All components: Touch-friendly on mobile, optimized for desktop
 ---
 ## Performance Considerations
 1. **Image Optimization**
   - Uses Next.js Image component for automatic optimization
   - Proper sizing attributes
   - Lazy loading for below-fold images
 2. **Event Cleanup**
   - Preview URLs revoked on unmount
   - Event listeners properly cleaned up
   - Timers cleared on component unmount
 3. **Efficient Rendering**
   - Minimal re-renders
   - Optimized state updates
   - CSS transitions over JavaScript animations
 ---
 ## Browser Compatibility
 Tested and working on:
 - Chrome 90+
 - Firefox 88+
 - Safari 14+
 - Edge 90+

 ## Notes for Frontend Lead
 These components are ready for integration into `/apps/landing/src/app/demo/upload/page.tsx`.
 **To integrate:**
 1. Import components from `@/components/demo/upload`
 2. Use FileDropZone for file selection
 3. Show UploadProgressBar during upload
 4. Display UploadResultCard for each successful upload
 5. Add zoom modal for full-size image viewing
 **API Integration Points:**
 - `onFileSelect` in FileDropZone - trigger upload API call
 - Update progress state during upload
 - Create UploadResult from API response
 - Handle errors appropriately
 The components handle all UI concerns - you just need to wire up the API calls and state management.
