Oil, Water, Glyph

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.

Along lines, digits must strictly increase or decrease.
