/**
 * src/css/ui-dialog.css
 * Shared in-app dialog module (src/js/ui-dialog.js) — Wave 14 / Part E1.
 * Uses design-system.css tokens (loaded first on every page that includes
 * this file) so the dialog matches whatever page it's opened from.
 * Stacking: above nav/sidebar/dock (--z-dock is the highest existing token
 * at 9998); the dialog scrim sits one above that so it always wins.
