 * Ticket 0014-FE, Folge-Befund: pid 569 (/products/graphics-and-multi-display)
 * nach dem IQS4-Kategorie-Re-Import. Container und ihre Kinder sind intakt,
 * aber: 8 Duplikat-Karten top-level in colPos0 (11853-11860) und die Grids
 * stehen falsch relativ zu ihren Intros (11840 vor 11629, 11841 vor 11632).
 *
 * Reparatur: Duplikate soft-loeschen, colPos0 in Sektions-Folge neu sortieren.
 *
 * Usage:  php migrations/fix_graphics_grid.php          (inspect)
 *         php migrations/fix_graphics_grid.php --apply
