Explain its purpose in README

I mean, it is a pretty interesting game, especially if you're juggling the numbers and combination possibilities entirely in your head.

If anything, it is a conversation piece about the uniqueness of games, the assistance of visual aids, and how that is unexpectedly flipped for the computer (analyzing subset sums is easier than grid alignment, even in code).

I should probably add more to the README but it will all go in the site's copy.

+I don't expect it to be fun -- I made it as a vehicle for a tutorial about setting up VitePress and putting together a basic Vue3 site.  I made it for a few specific people but if you also find it useful, great!
