The puzzle

Rules

Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and box.

Windoku: Each of the four shaded regions contains the digits 1 to 9 once each.

Arrows: Digits on arrows sum to the total indicated by the arrow's circle.

Black dot: Digits separated by a black dot are in 1:2 ratio.

Diagonal sums: Digits on a diagonal marked by a little arrow outside the grid sum to the indicated total.

Strong zipper lines: Every pair of digits on a pink zipper line that has an equal distance to the center cell of the line contains the same digits in any order, and sums to the total indicated by the digit on the center cells.

For example, a zipper line could read 22755 or 25725, but not 23745 because the pair of digits 2,5 is not the same as the pair of digits 3,4.

What a hidden gem! Superb puzzle right here. Some amount of theory is required

Thank you for your wonderful compliments Selena! This was one of those puzzles that took me weeks to come up with, partly because I was still very new at setting, and partly because I was exploring so many different ways to go in a windoku. I'm so happy that you like it so much!
