File	Description
package.json	Updates all dependency versions with major bumps to React 19, Tailwind 4, Firebase 12, and various minor/patch updates
yarn.lock	Comprehensive lockfile update reflecting all transitive dependency changes from the package.json updates

Note: No issues were identified during this review. The dependency updates appear consistent between package.json and yarn.lock. However, given the scope of major version updates (especially React 19, Tailwind 4, and Firebase 12), comprehensive testing should be performed to ensure no breaking changes affect the application functionality.
