Initial cost solution:

typical glyph config, the puzzle is how to bond the product

using v-shape intermediate can get 2-atom on the desired inaccessible bonding position, and 1 grabbed atom which must be the quicksilver for projection

thus we must prevent leaving any singleton atom while crafting the v-shape

some paper work leads to a simple method, the snake-shaped intermediate which can be easily broken into 2 v-shape

implementing the process take almost no effort for its simplicity

swing footprint might have some room for optimization

Update (-3A):
optimized the sequenced for a little bit, this must be very closed to optimal if not winning

Update 2 (-2A):
turns out that secondary could be even smaller
this still runs the same process, but the layout is radically different
the new output position no longer requires changing the grabbed atom from the bonding state
I thought this could be 22a at the first glance, but unbonding the v^-shape must use 2 excess hex during swing, and calcifying also took that hex to complete

Update 3 (-1C):
swapped output position so this is one cycle faster, there is a chance that this really matters

Update 4 (-2A):
last minute save, juggling the layout results in an even smaller area, this MIN +2 is unthinkable at first but astonishingly possible
could cut 1 more area if calcifier could be placed in the bottom-right hex 3-tile to the arm, which require some wand to use that is probably impossible to achieve
