Y1n-Y9ng SL Star Battle

Normal sudoku rules apply.

Yin-Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is either fully shaded or unshaded.

White dots lie on the border between the shaded and unshaded regions. Additionally, white dots separate consecutive digits. Not all possible dots are shown.

Sight Lines: Digits in caged cells show the number of cells of the same color (shaded or unshaded) seen orthogonally from that position, including itself. The "other" color blocks vision.

Star Battle: Put exactly two stars in every row, column and box such that no stars touch each other, not even diagonally. You can put stars on 1's and 9's only.

All 1's are in the shaded region. The two given 9's are in the shaded region; the other seven 9's are in the unshaded region.
