Oil, Water, Extenban

Oil and Water Puzzle Pack
II : Oil, Water, Extenban
Normal sudoku rules apply.
Each cage is either full of "oil" (even digits), full of "water" (odd digits), or a mix of both. In all cases, each "row" within a cage is of just one type (oil or water). Oil floats on water, so even digits will always be in rows above odd digits in mixed cages.
Digits in cages do not repeat.
Digits in cages must sum to the small clue, if given.
Digits along a pink line form a consecutive group in any order. Digits do not repeat on the line EXCEPT for the ends, which are the SAME digit. For example, possible fills for a line of length 4 might be 6456, 7867, 1231, etc.

Oof I didn't read the rules correctly and just assumed it was a regular renban. When I kept hitting a wall after a few tries I finally reread and afterwards a smooth solve.

I really liked the constraints on this one. Unique enough to change my thinking process but not different enough for me to constantly check the rules. Very fun and smooth puzzle!
