- Add lazyScreen() utility wrapping React.lazy + Suspense - Lazy-load MobileCourseViewer and MobileQuizManager in route files - Convert src/screens/index.ts barrel to lazy exports
perf: add lazy loading and code splitting (rinafcode#144)
- Add lazyScreen utility using React.lazy + Suspense - Lazy-load MobileLogin, PaymentHistory, SettingsScreen in src/screens - Export lazyScreen from src/utils/index.ts - app/course-viewer.tsx and app/quiz.tsx already use lazyScreen - expo-router provides automatic per-route splitting; lazyScreen adds component-level splitting for heavy screens within routes
