Tighten the reins

Rules
Normal sudoku rules apply.
The grid is covered in fog. Placing a correct digit will clear the fog from that cell and potentially from other cells somewhere in the grid.
Box borders divide each blue line into segments with the same sum.
Along orange lines, adjacent digits differ by at least 4.
Along green lines, adjacent digits differ by at least 5.
Along pink lines, digits form a consecutive sequence in any order.
Digits cannot repeat within the same constraint type, and lines do not share cells.
Solution code: Column 8

Very nice! I kept looking in the wrong places, so my solve time was really long. Still got to the finish line, so that was rewarding. Thank you

Great one! I really like the symmetry that the break in implied. Not good at Dutch whispers so struggled at the orange lines a lot.

ND: Thank you for solving! Indeed the orange lines are the trickiest part.
