πŸ’‘ What: Implemented code splitting for the GameRoom route using React.lazy and Suspense.
🎯 Why: The GameRoom component and its dependencies (antd components, sub-components) were being bundled into the main entry chunk, increasing the initial load time of the application even for the landing page.
πŸ“Š Impact: Reduced the initial JavaScript bundle size from ~1.08MB to ~770kB (a ~28% reduction). The GameRoom code (~311kB) is now loaded on demand.
πŸ”¬ Measurement: Verified by running npm run build before and after changes and comparing chunk sizes. Also verified functionality via Playwright script to ensure the route still loads correctly.
