/* When displayed via JS, flex will be set inline or via class, but usually JS sets display: block or flex. 
   If JS sets display: block, we need to ensure it uses flex for centering or use absolute positioning.
   Common pattern: class 'modal' is hidden, class 'modal show' is flex. 
   But report.js simply sets style.display = 'block'. 
   So we need to make sure .modal[style*="block"] behaves like a flex container or handle centering differently.
   Actually, if JS sets display: block, we can't use flex centering on the parent easily without !important or changing JS.
   Better: Change JS to set display: flex? Or use absolute centering.
   
   Let's use absolute centering for .modal-content if parent is block.
