/* Migration Recon Gate · center layout ONLY. Palette, header, buttons,
   tiles, badges, ledger, footer, focus rings all come from app-base.css.
   This demo's distinct mechanic: a locked gate bar pinned above the run
   buttons, batch cards that hash themselves in sequence with three tier
   rows each, a to-scale coverage strip, and a side-by-side record diff
   with the differing field highlighted. No palette redefinition. */
