• The lockfile updates @next/env/next to 16.1.5, but @next/eslint-plugin-next (pulled in via eslint-config-next) remains at 16.1.1. After bumping eslint-config-next to the matching Next.js version, regenerate package-lock.json so the plugin/config versions are aligned with the upgraded Next runtime.
