The tower's drawing straddles the map boundary -- roof band and top
window courses in Route 10's last rows, the rest in Lavender -- so each
map folded its half upright alone: two half-buildings, Lavender's under
a fabricated yellow cap.
Buildings templates gain `topRows`: drawing rows composited ABOVE the
matched grid, for a drawing no single map holds. The model is built
from the complete 16-row artwork (96px facade under the real 32px
purple band) while placement still matches only the on-map rows; depth
now derives from the matched footprint rather than sprite height,
identical for every whole-drawing template. A `claimOnly` twin template
claims Route 10's roof rows and stamps nothing, so the top half no
longer also stands as its own building. Both templates verified to
place exactly once, world-wide, at the intended coordinates.
A body-anchored building's eave juts frontEave voxels past the map
boundary; the neighbour-body mask read that overhang as a ring scrap
and opened the roof rim into the sky from across the seam. Building
placements only scan the body, so their quads now carry an `own` flag
the edge keep-rules never touch.
