FuzzyGrim/Yamtrack ? reverse-engineered prompt

Build me a self hosted media tracker where I can keep tabs on everything I’m watching or reading in one place, like movies, TV shows, anime, manga, games, books, comics, and board games.

I want to be able to sign in as multiple users, add items to a personal library, mark progress, status, scores, rewatches or rereads, dates, and notes, and see a history of what I changed over time. It should also let me make custom entries for things that don’t exist in the usual sources, and create lists I can share or collaborate on with other people.

Please include a calendar for upcoming releases, support for notifications, and a way to subscribe to the calendar in other apps. It should also have import and export so I can bring in data from popular tracking services and save everything to CSV. If you need current docs or setup details, look them up online as you build it.
