   If the original 4-stat cards view breaks, we'll need a new class for this chart grid.
   Let's check base.html or other pages to see if .stats-grid is used elsewhere with different column expectations.
   The example HTML used it for 4 stat cards.
   The current report_web.html uses it for the event-specific charts.
   The example HTML from user also had a .stats-grid for 4 items.
   It is safer to make a new class or make this one more specific if it's reused.
