   BS5 Modal compatibility with BS2 CSS
   =========================================================================
   BS2 positions .modal with fixed positioning and uses top:-25% -> top:50%
   slide-down animation via the .in class. BS5 JS adds .show instead of .in.

   This shim replicates the BS2 animation: the .modal starts at top:-25%
   (off-screen above) and transitions to top:50% (centered vertically).
   Horizontal centering uses transform:translateX(-50%) with left:50%.

   ALL .modal-dialog rules are scoped to .modal.show so they never affect
   legacy popups that contain a .modal-dialog child but are shown via
   ShowCenteredDiv() (which never adds .show).
