Dependency & Environment Audit

• Identified outdated packages, deprecated Cloudinary SDK methods, and security vulnerabilities using ecosystem-appropriate tools (npm audit, pip check, etc.)
• Defined the target upgrade stack per app's native tech stack (e.g., Node.js LTS, Next.js 15+, React 19, or Python 3.12+ / Vue 3, depending on the app)
• Upgraded the underlying frontend framework (React / Next.js / Vue)
• Ensured Cloudinary's Generative Fill and AI background removal features use the newest SDK syntax
• Fixed broken UI components and outdated multi-image layout styles
