/* ===== NextERP — DXF Nesting (Phase 33) =====

   House rules, as production.css:
     - no new colours: every value is a var() from app.css :root, so dark
       mode follows the theme with no extra rules;
     - logical properties only, so Arabic and Kurdish mirror with no overrides;
     - everything prefixed ns- or scoped to #nestScreen.

   One deliberate moment of motion: the Step 2 dial. It stops under
   prefers-reduced-motion and the seconds counter still ticks. */
