1. User uploads app screenshots and writes a short brief in the dashboard composer
2. AI analyzes uploaded screenshots to extract colors, mood, features
3. AI outputs JSON design specs (layouts, text, decorations, badges)
4. HTML/CSS renderer builds pixel-perfect designs from JSON
5. Puppeteer captures designs as store-ready PNGs

• No preset colors: AI extracts palette from actual app screenshots
• No hallucinations: AI never fakes ratings, downloads, or reviews
• HTML/CSS rendering: not AI images, pixel-perfect deterministic output
• 250+ emojis across 25 categories via Twemoji CDN
• 50+ decorative shapes (sparkles, blobs, glows, geometric)

• npm run dev - Start dev server with auto-open
• npm start - Start server without auto-open
• npm run export - Export designs to PNG via Puppeteer
