Qi Manifest (Yin Yang Sum Lines)

Qi Manifest
I have wanted to try my hand at a Yin Yang / Sudoku hybrid for quite a while now - in my opinion, the inherent rules around shading create a unique base for other constraints. This shouldn't be a very tricky puzzle, but the constraint interactions should present some new and interesting ideas. Your feedback is appreciated, and I hope you enjoy Qi Manifest :)Rules
- Sudoku: Normal sudoku rules apply.
- Yin Yang: Shade the grid using two colours, such that all instances of each colour are orthogonally connected, and no 2x2 area is completely one colour.
- Shading Sum Lines: Blue lines must have an equal sum N within each colour they pass through. If a blue line passes through a colour multiple times, each individual pass sums to N. All lines must cross colours at least once.
- Ratio: Two digits separated by a black dot have a ratio of 2. Not all dots are given.

Beautiful interaction between the line constraints and Yin Yang logic.

Do every blue lines have to be in both shaded and unshaded regions? I understood so. I'm just trying to figure out if I got it wrong as I'm stuck with Box 1.

Yes - it was hard to word it completely unambiguously, but every line must have at least one cell in each of shaded/unshaded. For example, if there was a two-cell line, that would always have to be the same digit but with different shading on each cell.

Great puzzles!
Although there was a stuck point in the middle that I didn't figure out clearly, it took a few minutes, the whole solution process was quite pleasant, thank you!
