Thanks! I've been ill so just getting around to looking at this now.
I've left some comments below, but it looks on the right track.

Both files need license information attached.
Following existing conventions in Spectrum, this should be:
- MIT for flake.nix
- CC0-1.0 for flake.lock
Since flake.lock is a generated file, you can put the license
information in a flake.lock.license file — there are other examples of
this in the tree you can refer to.
You can do a basic check that the license information looks right by
running `reuse lint`.

We should probably list only supported platforms here, right?
