  /* A card that just wraps the report's data table can be many pages long
     (a stock list, a transaction list, ...). Forcing page-break-inside:avoid
     on it (like every other card) makes the whole table jump to the next
     page as a block, leaving the first page almost blank under the KPI
     boxes. Let this specific card flow across pages instead, and repeat
     the table header + keep each row intact so it still reads cleanly. */
