Position inactive heaven beads much closer to top edge (7pt from top)
to create maximum visual separation from reckoning bar (13pt gap vs
previous 6pt gap).
This provides much better visual balance with the large gap that
inactive earth beads have from the reckoning bar, while keeping
heaven beads clearly in the upper portion of the soroban.
Updated all example images to show the maximized positioning.
