Build me a mobile first website for a student run Free Fire tournament at NIT Hamirpur. I want a clean public site with pages for the main tournament info, Battle Royale, Clash Squad, schedule and results, leaderboard, room details, rules, and a status check page. It should also have an admin area with a private PIN sign in where I can manage registrations, set lobby fees separately for each mode, update schedules, track payments, set rooms, and publish dated results and leaderboard settings.

Make it feel polished and easy to use on phones, with a modern dark glass style, clear buttons, good spacing, visible focus states, and support for reduced motion. The app should save tournament data through a simple backend so changes persist, and it should work locally as well as on Vercel. If you need to check current docs for deployment details, do that. Keep it simple for users, but make the admin side powerful enough to run the whole tournament.
