Version 2 ... radically different joinery, and red oak this time.

Although the overall dimensions are about the same, I made the top step a
little bigger (for comfort and ease of standing) and the bottom step a shade
smaller. The step overhangs are a bit bigger with an under-bevel matching
the dovetail angle.

Although this one is more comfortable to stand on, and the joinery is more
fun, the overall proportions of the less-chunky original seem a bit more
appealing to me.

I still don't know which one I'll give away.
