Similarly to Ragna, I was actually way too tired for this, but it was such a nice puzzle I soldiered through it anyway

Really interesting the way this unfolds. I made a dumb arithmetic mistake at the beginning and wound up with a complete grid that only disobeyed the 28! But it was heaps of fun!

I just wanted to have a very short look on the puzzle... but then I couldn't stop solving. So exciting! So elegant. Thank you very much. :-)))
