Another, harder puzzle based on the "Ratio Lines" constraint found in my previous puzzle

• Sudoku: Place the digits 1 through 9 exactly once in every row, column, and 3x3 box.
• Diagonals: Along each indicated diagonal, digits cannot repeat.
• Kropki: Digits joined by a white dot are consecutive. Digits along a black dot have a 1:2 ratio. Not all dots are given.
• Ratio Lines: If two digits are adjacent on a gold line, one of them is a multiple of the other.
