/* ============================================================
   Screen Definition Editor (admin) page.
   Structure in @layer layout, paint in @layer design. Content-named
   classes only — no legacy/appearance names, no hardcoded color.
   Reuses .app-screen and .btn/.btn--primary/.btn--outline from
   elements.css.

   ADMIN page: system admins / prosecutors author screen definitions under
   the default light .app-screen palette. This stylesheet only references
   --t-* semantic tokens, which app/theme.css rebinds per theme, so the
   page reskins without any role-specific color rules here. The controller
   toggles / queries the state classes restyled below (is-selected on the
   active definition row, asd-status-badge--active/--draft on the row /
   editor status pill). The create / clone dialogs carry the .app-screen
   root class so the same --t-* tokens resolve when appended to the modal
   root.

   LIVE PREVIEW: the ScreenEngine / LayoutRegistry preview output renders
   INSIDE #asd-preview-container with its own engine-owned classes. This
   stylesheet only frames it via the .asd-preview panel — it never selects
   or restyles the engine's markup. See docs/FRONTEND-ARCHITECTURE.md.
