Strategic Suspense Boundaries

Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.

Code Comparison

•Incorrect (wrapper blocked by data fetching):tsx
•Correct (wrapper shows immediately, data streams in):tsx
•Alternative (share promise across components):tsx

Why This Matters

Impact: faster initial paint. This optimization is classified as HIGH priority for production applications.
