Normal sudoku rules apply.
Digits an equal distance away from the center of a lavender Zipper line must sum to the digit in the center of that line.
I think a relatively approachable introduction to the zipper line constraint, but it produces some unexpected logic.
Solution code: Row 5

I agree with the logic being quite surprising. Nice!

Very fun solve, and I'm not that fond of Zipper lines. Very well done!
