/**
 * Ticket 0014-FE Punkt 1: /products (pid 447) ohne Grid-Container im Payload.
 *
 * Befund (check_grid_447.php, 2026-10-28): der Portfolio-Re-Run (IQS4) hat
 * die 15 vitec_cols_33_33_33-Container VERSTECKT (hidden=1, uid 11794-11808;
 * ihre 38 Original-Karten stecken intakt und bebildert darin), 38 neue
 * Duplikat-Karten top-level in colPos0 angelegt (11861-11898) und die
 * Sortierung neu verteilt - die versteckten Container stehen dadurch an
 * falschen Positionen.
 *
 * Reparatur: Container einblenden, Duplikate soft-loeschen, colPos0 in der
 * P5-Reihenfolge (Intro -> Grid(s) -> naechstes Intro, danach Banner/FAQ in
 * bisheriger Folge) mit Stride 256 neu sortieren.
 *
 * Usage:  php migrations/fix_products_grid.php          (inspect)
 *         php migrations/fix_products_grid.php --apply
