Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Lazy-loaded pages can become unusable if a route chunk fails to download because the current loading fallback does not provide recovery. The change is otherwise mergeable with explicit owner awareness to add retry or reload handling. Suggested labels: Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Add recovery for rejected lazy imports.
Suspense handles pending React.lazy imports only. A rejected page-chunk import reaches the nearest Error Boundary. src/main.jsx mounts App without an Error Boundary, so a failed page chunk can leave the selected route unusable. Add an Error Boundary with a retry or reload action.
