[This puzzle comes from the 2022 US Sudoku Grand Prix round. Shape Sudoku is a variation I created many years ago where careful assignment of the givens to each of the shapes can lead to fun and narrow solving paths, so I really enjoy setting these kinds of puzzles. I had one big idea for the “eight” theme which you’ll certainly see while working through to the solution.]
