Build me a modern web app called EcoQuest for an office environment that motivates people to do eco friendly actions and earn points. I want a clean dashboard where users can see their points, streak, level, and progress at a glance, plus daily missions they can complete, a leaderboard, and department challenges so teams can compete in a fun way.

Include a QR scanner flow so people can verify completed missions, a marketplace where they can spend points on rewards, a carbon calculator with simple tips, and an impact page that shows real world effects like CO2 saved, trees planted, and plastic reduced. Add login and registration, a profile page, and a simple onboarding guide so new users understand the app quickly.

Make it feel polished with light and dark mode, smooth transitions, and a friendly, playful visual style. Use the existing React and TypeScript setup, and if you need current docs for any libraries, look them up online.
