This puzzle was created for Scojo's weekly setting prompt. This time the theme was Modular Lines and Parity. Thanks to Jennyaa for testing. All feedback is appreciated. Hope you enjoy, and thanks for playing!

Rules:

Sudoku: Place the digits 1-9 once each in every row, column, and 3x3 box.

Odd: The cell with the grey circle contains an odd digit.

Parity Enclaves: Within each 3x3 box, the odd and even digits will each form a set of orthogonally connected cells.

Modular Lines: Along a teal line, any string of 3 adjacent digits must include one cell from each of the sets {1,4,7}, {2,5,8}, {3,6,9}.

Crossing Guards: Digits in a teal circle indicate the number of times its line changes parity along its length.
