     whose content is always small and bounded (a fixed top-10/top-20 list, a
     5-card KPI grid, a single chart) the template wraps heading+content in
     .print-keep so the whole group is forced to move together - safe here

     wrapped this way, since forcing an arbitrarily long table to stay intact
