/* Modal positioning: keep dialogs clear of the docked sidebar.
   Bootstrap centers .modal-dialog within the full viewport by default;
   on desktop widths narrower than roughly 1330px a centered modal-lg
   mathematically extends left of x=264px (the sidebar's width), so the
   sidebar's own stacking context visibly overlaps the dialog there. Fix
   it at the source: on desktop, modals in the sidebar layout are only
   centered within the space to the right of the sidebar.
   app.js relocates every .modal to a direct child of <body> before init
   (see assets/js/app.js — fixes real mouse clicks landing on the
   backdrop instead of the dialog, a separate bug from this one), so this
   can no longer be scoped with a `.app-shell .modal` descendant selector;
   `body:has(.app-shell)` detects "this is a sidebar-layout page" instead.
   Standalone pages without a sidebar (login/POS) don't match and keep
   Bootstrap's normal full-width centering. */
