seiyria/tournamentmango ? reverse-engineered prompt

Build me a web app for managing tournaments and players in one place.

I want to be able to keep a roster of players, save their scores over time, and track things like their characters, games, and alternate names. I also want to create events and tournaments, where an event can hold multiple tournaments but I can still make a tournament on its own if I want. The app should generate brackets for single elimination, double elimination, free for all, round robin group stages, and a masters style free for all.

Make it easy to create, edit, and view everything, with a clean dashboard for tournaments, events, and player records. If you need to look up current docs or best practices for anything, go ahead. I mainly want the core tournament and player management flow working end to end, with data saved and reused across the app.
