Thanks to everyone for all your comments and photos. I ended up making 4 shelves that go completely side-to-side and front-to-back. I ripped some 3/4" pieces of 1x stock to give a square 3/4" x 3/4" piece. I used these pieces at varying lengths to make frames for the shelves as well as corner supports that go under each corner of each shelf. The corner supports are the lighter wood in the third picture -- they are not installed yet but in their approximate position. The shelf is about 3/16" thick luan, so it's probably 1/4" stock (don't you just love lumber yard math?).

Each shelf weighs about 3 lbs 3 oz, so that's about 13 lbs. With the "add-a-shelf" closet thing and closet rod I removed, it's about a 10 lb net gain, which, as I found out, is significant. The wardrobe definitely feels a bit bloated now with some stuff in it. I think with the center cross supports I have on each shelf, I could have gotten away with thinner luan to reduce weight.

The shelves are all glued together and to the corner supports, which in turn are glued to the wardrobe.
