- Remove external next-view-transitions dependency - Use Next.js 16 native navigation and Safari 18+ native View Transition API - Add ViewTransitionProvider for minimal wrapping with Safari 18+ detection - Updated all Link imports from external package to next/link - Removed link-wrapper.tsx and view-transitions-wrapper.tsx This resolves Safari compatibility issues while maintaining transitions on modern browsers.
