React version conflict between dependencies and resolutions

The dependencies section specifies react and react-dom at version 19.x, but the resolutions section forces ^18.x for both. Yarn's resolutions field overrides nested dependency versions across the entire dependency tree, creating a direct conflict with the top-level dependency declaration. This mismatch can cause installation failures, runtime errors, or the notorious "multiple React versions" problem where hooks and context fail silently. The @types/react in devDependencies also remains at ^18.x, further exacerbating type compatibility issues with React 19.
