Today's GAPP is a Ring-Ring (Black & White)!

There's a month-long Ring-Ring contest currently happening over at Puzzle Duel. This is one of the variants featured (called Black Ring White Ring on the website) which I thought was quite nice. I don't think I'll set a puzzle for the variant featured today, though...

Rules: Draw rectangular loops through the centers of cells so that every cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. Given circles must lie at the corners of rectangles. If a circle is black, the rectangle it is a part of must be square. If a circle is white, the rectangle it is a part of must not be square.
Note: Loops may contain multiple circles!
