I solved with
geoas well. Brute force to all possible rectangles from the polygon points. Tried to run it but after 30 seckilled it and just importedrayon. It's under 3 sec. There is no shame using libraries, it's part of the puzzle to know whics one is useful ๐I find it helpful to use a library to get the solution, and then work backwards to replace the library. I got rid of geo and got mine down to milliseconds.
