🚀 Service Worker = Faster Site
BolaPrediksi.org pakai Service Worker untuk cache assets, jadi site bisa load offline (atau super cepat saat 2nd visit).
📊 Strategy:
- Stale-while-revalidate: Tampilkan cached version dulu, lalu update di background
- Network-first: Untuk berita, livescore (must be fresh)
- Cache-first: Untuk static assets (CSS, JS, image)
⚡ Performance Impact:
- First visit: ~1.2s LCP
- Repeat visit: ~0.3s LCP (4x faster!)
- Offline mode: Page tetap accessible
