   Export Orders Management — application stylesheet.

   The design system is carried over from the approved HTML prototype: the same
   "Green ERP" palette, radii, badge treatments, table styling and card shells,
   so the refactored application looks like the prototype it replaces. What has
   changed is underneath — every screen is now driven by the live API instead of
   in-page fixtures.
