The volume repeat scan anchors at a column's front tile; a plateau
column ending in a rounded corner tile ($13/$35) never matched and
read its whole capped extent -- 48px fins and tents out of the 16px
mesas on Routes 3 and 4. When the two rows directly above the front
are identical, the column is that repeat wearing a trim foot: unit is
one course plus the trim. Doorway columns still answer to their
region first.
The cliff drawing's dark east slope ($02/$24/$34) broke the repeat scan
at its corners and rose to 32px towers; a folded doorway column read
its own drawn extent and towered a block over the 16px mound around
Diglett's Cave. The slope chain is pinned to one 16px course, and a
doorway column now takes height AND top from its region: roofed among
drawn facades (houses), flat among flat repeats (the mound). Adds the
voxel_mound_probe driver that prints per-column detector decisions.
Flowers stand as 1px animated cutouts on their own pulled mesh (own-cell
flowers hide behind the walker, the cell south still overdraws feet).
Cuttable bushes, gym statues (single-block plinth) and Lt. Surge's trash
cans stand as 5-voxel prop cutouts; prop_ground names the tile painted
beneath. Block edits refresh meshes in place instead of blinking to 2D.
