Moving To Suspense
summary
Argument rejects a full rewrite and shows an incremental path over days not months using concrete APIs and a working demo app that removes spinners and caches responses. Steps include enabling React StrictMode, switching to createRoot to opt in to Concurrent Mode, replacing manual splits with react.lazy and wrapping UI in React.Suspense, using react-cache image resources with low quality placeholders and a maxDuration set to 500ms so high‑res images swap in and album JSON stays cached while invalidation remains experimental.
