CC6a (index->ObjDesc factory + static-pose offscreen renderer) and
CC6b-PRE (idle loop, rotation, zoom, alternate-setup plumbing) both
closed through dual-lens review -> fix round -> narrow re-review. The
branch carries its own cross-branch renumbering (TS-84, ISSUES #403) so
this merge is number-clean against the CC4 rows.
Notable review outcomes carried in: the barber refutation (chargen has
NO alternate-setup checkbox — all five write sites are gmBarberUI), the
idle-by-default finding with its corrected InitializePage evidence, and
the 180-degree initial heading owed to the mount half.
