-## Preload Based on User Intent
-
-Preload heavy bundles before they're needed to reduce perceived latency.
-
-**Example (preload on hover/focus):**
-
-```tsx
-function EditorButton({ onClick }: { onClick: () => void }) {
-  const preload = () => {
-    if (typeof window !== 'undefined') {
-      void import('./monaco-editor');
-    }
-  };
-
-  return (
-    <button onMouseEnter={preload} onFocus={preload} onClick={onClick}>
-      Open Editor
-    </button>
-  );
-}
-```
-
-**Example (preload when feature flag is enabled):**
-
-```tsx
-function FlagsProvider({ children, flags }: Props) {
-  useEffect(() => {
-    if (flags.editorEnabled && typeof window !== 'undefined') {
-      void import('./monaco-editor').then((mod) => mod.init());
-    }
-  }, [flags.editorEnabled]);
-
-  return <FlagsContext.Provider value={flags}>{children}</FlagsContext.Provider>;
-}
-```
-
-The `typeof window !== 'undefined'` check prevents bundling preloaded modules for SSR, optimizing server bundle size and build speed.
