The rest gap after completion doubled up: the status overlay reserved
its own end inset on top of the footer's 10vh spacer. The overlay now
floats within the spacer zone — its height feeds only the glide target
(the live line still rests above it), the list gets no extra inset, and
completion cannot shift layout because there is nothing to collapse.
The finished message's metadata lands in the slack the glide left above
the status row, restoring the old morph-in-place feel. The frozen
height hack and the opaque background are gone — the overlay only ever
covers blank spacer, not text.
