2. Share button ✅
Web Share API on mobile, clipboard fallback on desktop.

3. Multi-language support — 8 languages ✅
🇺🇸 English | 🇧🇷 Português | 🇪🇸 Español | 🇫🇷 Français | 🇩🇪 Deutsch | 🇹🇷 Türkçe | 🇯🇵 日本語 | 🇰🇷 한국어

Full UI translated for each language: titles, buttons, categories, results, share messages. Language selector with flags available on all screens.
