/* =====================================================================
   Archi Invoice - stylesheet tunggal
   ---------------------------------------------------------------------
   Palet merek: oranye #FF7043, hitam #0D0D0D, abu #B3B3B3, putih #FFFFFF.

   Catatan kontras: teks putih di atas oranye merek hanya 2,7:1 - gagal
   WCAG AA. Karena itu tombol oranye memakai teks HITAM (7,6:1), dan
   untuk tautan dipakai varian oranye yang lebih gelap (--accent, 5,2:1
   di atas putih). Marka logo memakai aset transparan berwarna putih.
