Min cost, min+1 area

Lustrous syrup tech again. Triangles end up working really well here.
I do want to check at some point to see if making the triangles the other way around is faster, because avoiding the calcification glyph (and debonder) requires a lot of shuffling right now. 

Could there ever be a layout with lower area at this cost? Hmmm.....
Don't know yet if that's worth searching for
