Polish & Quality of Life
- Smooth page transitions - all pages now fade in seamlessly on navigation and refresh, with lazy-loaded content appearing together instead of popping in one by one
- Unified loading indicators - replaced skeleton placeholders with a clean, consistent spinner across the entire site
- Improved error resilience - profile loading, dashboard, and game stats no longer get stuck if a network request fails
- Avatar reliability - fixed avatar not updating after upload or when switching between image sources
