1:1 Aspect Grid (Square)

A square version of an evenly-spaced grid. I would argue this might be the least desirable option, because (a) it’s not much more interesting than the 3:2 grid, but (b) it will add a lot of work to crop a square version of each post. So lots of work with little benefit… go with 3:2 if you’re OK with evenly spaced items.
