Normal sudoku rules apply (fill each row, column, box with the digits 1-8 without repeats)

Cells separated by white Kropki dots (which contain no symbol) are consecutive. Not all dots are given.

Binairo (or as LinkedIn calls it, Tango):
Every cell is either a Sun or a Moon. Some Suns and Moons have been marked (yellow circles and blue rhombuses, respectively).
Each row and column contains 4 Suns and 4 Moons. You can't have three Suns forming a straight vertical or horizontal line. The same applies to Moons.
Cells separated by an "=" are of the same type (two Suns or two Moons).
In this puzzle, Suns contain odd digits and Moons contain even digits.

Star Battle (or as LinkedIn calls it, Queens):
Each region (nation?) contains exactly 1 Queen. Some are already marked with a crown.
Two Queens can't be in the same row or column. They also can't be a chess king's move away from each other.
Despite their name, they can be in the same diagonal, just as long as they aren't adjacent.
In this puzzle, each Queen bears the digit corresponding to her nation's assigned number.

For reference, the boxes are arranged as follows:
1 2
3 4
5 6
7 8
