• Vite: A fast build tool for modern web development.
• TypeScript: For type safety and an improved developer experience.
• Tailwind CSS: For rapid and consistent UI development.

Note: Some parts of the codebase still use legacy structures from the original implementation. Contributors should expect gradual updates as testing and refactoring continue.
