Build me a simple roster update app based on the information in the PDF I already have.

I want something that lets me view the current roster, add new people, edit details, remove entries, and keep everything organized in one place. It should be easy to use, clean, and work well on desktop and mobile. If it helps, you can use the PDF as the starting point for the data and turn it into a more usable interface instead of making me dig through the file every time.

Please make the layout straightforward, add basic search or filtering if it fits naturally, and make sure the data can be saved properly so updates do not get lost. If you need to look up anything current in the docs or web while building it, go ahead and do that.
