RetailFrameWalk composes the ported machinery into retail frame shapes:
SmartBox::RenderNormalMode rooting (camera-cell low word < 0x100),
PView::DrawInside + the DrawCells event half (interior pview, the
traces pv=009d4a80), LScape::draw (per-view visibility, blocks
far-to-near, per-block cells far-to-near, buildings at their cell turn)
and RenderDeviceD3D::DrawBuilding (BLD at entry before the degrade
check; two-pass BSP portal walk per active view on the outdoor pview,
the traces pv=009d4b08). WalkLandscape ports the block grid +
draw_check_blocks/landcell_check visibility (192 m/24 m pitch,
viewer-relative, union across views, never downgrade). Six composition
tests: outdoor far-to-near emission, degrade-entry event, interior
ov=0/ov=1 shapes, rooting, complete view unwind.
