::: aside / .margin blocks no longer split the column segments: they
stay inside the .colseg at their anchor point, so the surrounding text
is measured and laid out as a single columned layout (split-off sides
previously lost .cols when too short on their own).
The zone placements (multicol side zone, sidebar track, wide gutter)
now position the boxes absolutely off the article's left border —
unaffected by any column layout inside — with the vertical spot coming
from the unset top (where the box occurs in the text). Narrow widths
keep the in-column float fallback. Trade-off: out-of-flow boxes no
longer stack via clear, so boxes anchored close together may overlap.
