Mirror Steps

This puzzle was created for Scojo's weekly setting prompt, initiated by Calvinball, which challenged setters to make a reflection themed puzzle.
I hope you enjoy solving it!

Rules:
Normal sudoku rules: Place the digits 1 to 9 in each Row, Column, and 3X3 box.
Parity mirror: The marked diagonal acts as a parity mirror. Digits above/right to the mirror reflect their parity to those below/left (e.g. if R5C8 is even, then R8C5 is also even).
Region Sum Line: Digits along the Blue line sum to the same total in each 3x3 box the line passes through.
Renban: Digits along a Purple renban line form a sequence of consecutive digits in any order.
Kropki: Cells separated by a white dot must contain consecutive digits. Cells separated by a black dot have a 1:2 ratio. Not all possible dots are given.
Solution code: Row 9 digits from left to right.

For a moment in there, I was stuck and thought of giving up. Then the continuation was so satisfying.
If you get stuck, focus on relationships in boxes 6, 7, and 9.
Thank you palpot for creating, and James Sinclair for recommending.
