Spread Out Quietly
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Digits in cells separated by a green line must differ by at least 5.
The pink(?) lines are entropic lines: any consecutive group of three cells along an entropic line must contain a low (123), a medium (456), and a high (789) digit.
