   Each regional deployment shows only its own market. What was

   quote + LATAM column) collapses to a single-column narrative
   on each regional page. The CSS below re-centers the remaining
   child + promotes the axis quote to a standalone mid-section
   editorial break so the layout reads intentional, not orphaned.
   Body of the root / picker is market-neutral and inherits the
