/* Tandem comparison demo. Comparison state lives in native controls. A small page script coordinates
   the mobile page-to-table scroll handoff. Without it, ordinary nested scrolling works.
   The table keeps its composition in an explicitly scrollable region.
   Sticky row/column headers share that one scroll ancestor.
   No colspan: every header band obeys the same plan visibility as the data. */
