After measuring right and then checking against the adjacent wall, I discovered the metal brackets angle is slightly over 90 degrees. This causes the front to be about 1/4 inch higher than the back. Since I had put a shelf the whole distance across the first wall, when I would add a shelf on the second wall, the heights would be different in the back, but the same in the front. A tilt away from the wall. I remedied that on the second wall by putting composite shims under the top of the bracket against the wall. Now the brackets are level from front to back in addition to being level side to side.
Then came the hard part; the brackets on the first wall. Fortunately I am building this high enough that I can sit on a chair and put my head under the shelf. I loosened the top bolt on several brackets and started slipping shims in behind the bracket and tightening it back up. Now things are level.

That was good, outside-the-box thinking.
