Greptile Summary

This PR updates dependencies to address Next.js vulnerabilities, bumping Next.js from 12.3.1 to 16.1.6, React from 18.1.0 to 19.2.4, and modernizing the build toolchain. The prod branch was added to CI/CD workflows, which triggered linting and formatting updates across the codebase.

Key changes:

• Updated Next.js, React, TypeScript, ESLint, Tailwind CSS, and Playwright to latest versions
• Migrated to ESLint flat config (eslint.config.mjs) and updated Next.js config for deprecated APIs
• Changed TypeScript JSX setting from preserve to react-jsx for React 19 compatibility
• Removed unused imports and applied Prettier formatting across components
• Updated GitHub Actions to Node.js 24.x and latest action versions

Critical issue:

• tailwind.config.js has duplicate extend objects (lines 6 and 16) causing the first to be overridden, which will break custom animations and fonts

Confidence Score: 2/5

• This PR has a critical configuration bug that will break Tailwind styling
• While the dependency updates are necessary and well-intentioned, the duplicate extend object in tailwind.config.js will cause the custom animation and fontFamily configurations to be lost, potentially breaking the UI. The other changes are solid migrations to newer APIs.
• Pay close attention to tailwind.config.js - it has duplicate extend objects that must be merged before merging this PR
