It's only 1 below 50, but I'm still pleased to have a sub-50 design. I believe 45A is the absolute minimum because that's all the necessary glyphs plus the 5 area I'm left with if I arrange said glyphs tightly around the product and fill the remaining voids in its bounding box with equilibrium, but I'd enjoy being proven wrong. It was hard fought getting down to 49, so I'll take whatever this gets me. Two bonders wastes a fair bit of area (especially b/c it makes the volume the product needs to be moved around in bigger), but it allowed me to avoid a lot of really nasty swings with the incomplete product so it's probably worth it.
