The composite's own header renders "<N> shown" from @groups-filtered, and the
nested grid rendered its own "Total: <N>" line 139px below it. Measured live:
"2107 shown" and "Total: 2,107" — the same number twice, both above the fold.
That is the redundant-header shape the standing rule forbids (the hint lives in
the EXISTING header, never a second one). show-total=false here matches the
pattern already applied in dashboard-plus-grid.vue:279 for the same reason.
The grid keeps its own total when embedded ALONE, where it is the only count on
screen — the prop is host-controlled, not removed.
Work started by a delegated agent that hit its session limit mid-task; verified
the cited sibling pattern exists before committing. check:sfc-parse and
check:template-literal pass.
