Why do MP3 files have a sample rate? (When they are just composed of sine waves)

I apologise if the title wasn't clear, but essentially, I am a little bit confused about MP3 files. I was under the assumption (in MP3s) that a Fourier transform is used to split up the sound wave ...

How can resynthesis engines be so accurate despite the time/frequency resolution trade-offs inherent in Fourier analysis?

I'm looking at Harmor specifically, but my question is about resynthesis in general. I assume that Fourier analysis is how these engines break a sound down into its constituent partials with frequency,...
