• Real-time Image Generation (DALL-E-3 via Dedalus)
• Market Price Intelligence (Snowflake simulation)
• Price Lock Protection (FlowGlad simulation)
• NFT Certification (Solana integration)

The system uses advanced prompt engineering, real-time data processing, and sophisticated UI/UX to deliver a seamless experience from character selection to order completion.

# Start development server (http://localhost:5173)
npm run dev

# Build for production (outputs to /dist)
npm run build

# Preview production build locally
npm run preview

# Lint code (ESLint)
npm run lint

# Clean build artifacts
rm -rf dist

1. Start Dev Server: npm run dev
2. Open Browser: Navigate to http://localhost:5173
3. Make Changes: Edit files in src/ directory
4. Hot Reload: Vite automatically reloads on save
5. Debug: Check browser console for logs
6. Test APIs: Use test functions in console

The app exposes several debugging utilities:

// Test Dedalus image generation
window.testDedalusImage()

// Check sessionStorage
console.log(JSON.parse(sessionStorage.getItem('cosplayBuild')))
console.log(JSON.parse(sessionStorage.getItem('cart')))

// Clear session data
sessionStorage.clear()
location.reload()

// Test Llama generation
import { generateCharacterProfile } from './services/llamaService'
await generateCharacterProfile("Goku")

The app includes comprehensive logging throughout:

TryOnLab.jsx:

[TryOnLab] useEffect triggered: tierData, gender, or items changed
[TryOnLab] Dependency change detected
[TryOnLab] Starting AI image generation...
[TryOnLab] ✅ Image generation complete!

dedalusImageService.js:

Generating cosplay image with prompt: <prompt>
✅ Image generated successfully
❌ Image generation failed: <error>
Base64 length: <length>

Issue: Image not regenerating on changes
Solution: Check useEffect dependencies in TryOnLab.jsx, ensure selectedItemIds is memoized

Issue: Cart data lost on refresh
Solution: Data should persist in sessionStorage, check browser privacy settings

Issue: API calls failing
Solution: Verify .env.local keys are correct and have VITE_ prefix

Issue: Build errors
Solution: Run npm install to ensure all dependencies are installed

✅ 60+ feature implementations
✅ 4 real API integrations
✅ 11 sponsor integrations
✅ Comprehensive error handling
✅ Mobile-responsive design
✅ Production-ready deployment

• ⚠️ Image generation can take 10-30 seconds (DALL-E-3 limitation)
• ⚠️ SessionStorage cleared on browser close (expected behavior)
• ⚠️ Some animations may stutter on low-end devices

• Add loading skeleton screens
• Implement image generation queue
• Add persistent storage option
• Optimize animations for 30fps fallback

• Slow Generation: Show progress indicator, add cancel button
• Lost Session: Add "restore cart" functionality
• Animation Stutter: Disable motion on low-power mode

Q: Do I need all the API keys to run the project?
A: Only Groq and Dedalus keys are required for core functionality. Google AI and Stability AI are optional.

Q: Why are some sponsor integrations simulated?
A: To demonstrate value without requiring complex API integrations for every sponsor. Can be upgraded to real APIs later.

Q: Can I use this project commercially?
A: Check individual API terms of service.

Q: How do I add more characters?
A: Simply type any character name in CharacterScan. Llama will generate appropriate details.

Q: Can I change the color scheme?
A: Yes! Edit tailwind.config.js and update color values in components.

Q: Is the image generation really real-time?
A: Yes! Every cart change triggers a new DALL-E-3 generation via Dedalus API.

Q: What happens if API calls fail?
A: Services include fallback data and error handling to gracefully degrade.

Q: Can I deploy this to GitHub Pages?
A: Not recommended due to client-side routing. Use Vercel or Netlify instead.
