📋 Puzzle Rules:
• Normal Sudoku rules apply.
• Each digit along a green line differs in value by at least five from its neighbor.
• White Kropki dots separate cells with a value difference of one, black kropki dots separate cells with values in a ratio of 1:2. No negative constraint.
• Two cells separated by an X sum to 10; two cells separated by a V sum to 5. No negative constraint.
• Digits in killer cages are distinct and add up to the value in the left upper corner of the cage.
• Thermometer lines strictly increase in value from the bulb end.
• Thin gray lines without bulbs are palindromes and read the same in either direction.
