   Document-preview modal ergonomics (global)
   Defensive layering on top of Bootstrap 5 defaults. The 2026-04-22
   regression ("modal opens, body won't scroll, X/Close unreachable")
   kept resurfacing because the scrollable dialog's height computation
   depends on .modal having viewport height — and any theme that shifts
   .modal's containing block breaks that. Pin the dialog to viewport
   height and force pointer events on the chrome so nothing intercepts
   clicks on the close buttons.
