Happy Bristmas!

This is a fog puzzle, so guessing is not necessary and strongly discouraged! There is one unique answer which can be logically deduced from the rules and the visible and assumable parts of the grid.
This is a subset puzzle. A 'subset' contains nine digits from 1-9, but perhaps not all of them, and repeats are allowed.
Digits in cages sum to the value given in the corner.
Any two digits along a thin teal Sequence line have the same difference in the same direction. 1-2-3, 1-3-5, and 1-1-1 are all valid, but 1-2-1 and 1-2-4 are not.
Digits along thick grey "slow thermometers" must increase or stay the same from bulb to tip.
Place a subset of the digits 1-9 into each row, column, and box.
Click to play!
Solution code: The nine digits of the subset as they appear along the positive diagonal.

I wasn't sure if the initial line was a slow thermometer or sequence. I did some guessing.
