/* ============================================================================
   dialogs.css — Diálogos modales, menú contextual y BACKSTAGE (panel Archivo).

   Portado de Odyssey (`public/css/ribbon.css` §§7-9 + `public/css/dialogs.css`)
   CONSERVANDO LOS NOMBRES DE CLASE (`xl-dialog`, `xl-cm`, `xl-btn`, `fc-*`),
   porque ui/dialogs/dialog.js y ui/contextmenu.js se copian de Odyssey casi tal
   cual (CONTRACTS.md §ui). Se añade el alias `wd-` con el mismo estilo por si
   A5/A10 renombran el prefijo, y las clases .backstage / .backstage-nav /
   .backstage-panel que exige el contrato de ui/backstage.js (A10).

   Paleta y medidas: css/tokens.css (var(--wd-*)).
